After each update, these appear, and for libusb, the number slowly
increases (up to 185 now).  so far I have done the suggested "emerge
@preserved-rebuild", plus tried rebuilding every package mentioned but
after building, there is no change ...

Are you using an unstable version of gentoo, e.g. ~x86 or ~amd64?  The
only reason I know of for 'preserving' an old version is if there is also
a newer one, i.e. libusb-1.0.1, which is a ~ version.

On my ~amd64 machine I had both libusb-0.1.12-r5 and libusb-1.0.1.
I just deleted the 0.1.12 and revdep-rebuild found and rebuilt usbutils,
hal, and sane-backends with no problems, so there seems to be no reason
to have the old version unless you perhaps have the new version masked
on your machine for some reason?

Your assessment of the problem is incorrect. preserved-rebuild happens when 
you upgrade a package which other packages link to and causes brokenness. When 
the "used by" package is rebuilt, there is no need for the old live version to 
be kept (it's only consumers no longer do so) so it is unmerged.

Think of it this way:
revdep-rebuild finds broken packages after the fact when they are already 
broken.
preserved-rebuild detects those problems before they occur and takes measure 
to keep the system working meanwhile.

You will notice that after running "emerge @preserved-rebuild", revdep-rebuild 
almost invariably returns null results.

As for the OP, I can only guess what might be causing this. Let's start with 
obvious stuff:

1. Is portage the latest version for your arch?
2. What does revdep-rebuild return?
3. What is your arch, and is it a mixture of stable and ~?

I know I've used the @preserved-rebuild target in the past, but now:

#emerge @preserved-rebuild
!!! '@preserved-rebuild' is not a valid package atom.
!!! Please check ebuild(5) for full details.

Would it work if I had any 'preserved' packages on the machine?

That looks like a portage version that does not support sets - it doesn't seem 
to know what '@' means.

Did you downgrade portage?

If the set is empty, the error is something along the lines of "set has no 
members" or words to that effect

Why not post what version of portage you are using?  emerge --info
should do that.

Looks something like this:

root@smoker / # emerge @preserved-rebuild
emerge: 'preserved-rebuild' is an empty set
emerge: no targets left after set expansion
root@smoker / #

The system is quite a few years old - the original install was ~2000,
and has quite a few hardware upgrades/rebuilds in between.  Current (for
at least a couple of years) cpu is amd athlon barton 2500+.

Software is a mix of stable, ~x86 and pinned (mostly particular ~x86 at
the time) working versions to avoid some of the upgrade treadmill.

I think I had installed 2.2_rc15, and then that stupid forced downgrade
because someone wanted a version tested came in - I'll try sorting out
the portage version first as that looks like a possible culprit.

Your libusb is currently latest, your portage-utils and portage are not.

I honestly think that debugging this will be an exercise in futility unless 
you can find a reference somewhere that says which versions of which portage 
tools are incompatible with which other ones, and why...

I'm also not sure anymore about which portage version was first to support 
sets. What I did was blow my top at the forced downgrade of portage at Zac's 
whim, and unmasked portage. Lots of troubles immediately and at once went away 
when I did this.

I'd suggest you switch to ~arch and tolerate the upgrade treadmill. A lot of 
that is packages that are rapidly and often changing. If you sync and upgrade 
once a week or fortnight, you'll find you upgrade package X just once, not 
several times during that period.

Maybe that's why I remember using @preserved-rebuild once or maybe twice.
I'm running the same portage now on x86, ~x86, and ~amd64, i.e. 2.1.6.13,
which apparently doesn't know about sets.  portage-2.2_rc33 is masked on
my profiles.

The only reason it's masked is to force as many users as possible to use an 
earlier version so that it "can receive more testing and get better bug 
reports", and that was done by Zac himself. There is not a single technical or 
code quality reason for it to be masked, it's purely a human issue

Just unmask portage and be done with it, I can't recall the last time there 
was a valid problem with latest portage reported here so it must have been a 
very long time ago.

Though I seem to remember that at the time portage 2.2_rc was masked it
was stated to only be a temporary measure to force more people to test
2.1.6 and that the mask would be removed when 2.1.6 went stable - which
it has been for some while.

If you're going to run release candidate versions, at least run the
latest release candidate. rc15 hasn't been in portage for a while, we're
currently on rc33. Add ~sys-apps/portage-2.2 package.{unmask,keywords} to
ensure you have a valid version.

Re: [gentoo-user] Re: can fix preserved-rebuild ...

2.1.6.13 was the latest when ... - thats as kindly as I can think of the
person and his reasons for putting me through a lot of work as I didnt
notice the downgrade on one system in time.  If it was for security or
other reasons I could understand it, and maybe not agree with it ... but
just because he wanted some extra testing he decided to "play" with
users systems!  I agree with you that portage is usually bug free and
trustworthy ... but the trust aspect has been sorely tried.

On this system, I just left portage at what seemed to be a working
version to avoid the problems caused by the downgrade.  This was a few
weeks ago now, so they have probably been sorted, but I think it might
be better to upgrade and find another stable, working version.
