Hi,
even the most recent portage 2.2.0_alpha90 has difficulties handling
@preserved-rebuild especially after many binary emerge operations.
It tries to re-emerge the same packages again and again.
As a last resort I have to remove
/var/lib/portage/preserved_libs_registry.
But after that the old libraries are still hanging around and
revdep-rebuild won't since there aren't any broken libs or binaries
just some which are linked against old versions.
Is there an elegant way to find these old libraries? (Removing them
would alert revdep-rebuild afterwards).
Thanks for a hint,
Helmut.

man qfile and look at the section on finding orphan files.
Emerge portage-utils if you don't have qfile.

I just ran
# find /usr/lib* -type f -print0 | xargs -0 qfile -o | more
an was suprised how much orphans there are, already excluding the python
and perl stuff.
Here's some suprising stuff:
/usr/lib64/systemd/system/canberra-system-shutdown-reboot.service
/usr/lib64/systemd/system/console-kit-daemon.service
/usr/lib64/systemd/system/canberra-system-shutdown.service
/usr/lib64/systemd/system/udev-trigger.service
/usr/lib64/systemd/system/udev-control.socket
/usr/lib64/systemd/system/dbus.service
/usr/lib64/systemd/system/acpid.service
/usr/lib64/systemd/system/console-kit-log-system-restart.service
/usr/lib64/systemd/system/bluetooth.service
/usr/lib64/systemd/system/udev-kernel.socket
/usr/lib64/systemd/system/udev.service
/usr/lib64/systemd/system/alsa-store.service
/usr/lib64/systemd/system/console-kit-log-system-start.service
/usr/lib64/systemd/system/udev-settle.service
/usr/lib64/systemd/system/canberra-system-bootup.service
/usr/lib64/systemd/system/dbus.socket
/usr/lib64/systemd/system/alsa-restore.service
/usr/lib64/systemd/system/console-kit-log-system-stop.service
....
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.3/libmudflapth.so.0.0.0
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.3/crtend.o
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.3/libgfortran.so.3.0.0
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.3/libgfortran.la
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.3/crtprec80.o
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.3/libgomp.a
....
the gcc stuff is multiple pages long. But I don't think it's a good idea
to start messing with gcc's files.
And what's with the systemd stuff? I never even installed it.
This is a fresh stage3 install from about a week ago.
Any thoughts?

SNIP
I've found out a strange effect.
Many files in /usr/lib64 are NOT recorded by portage but only the
corresponding names in
/usr/lib
Therefore I've used
find -L /usr/lib -regextype posix-extended -regex '.*.so(\.[0-9])+'
-type f -print0 | xargs -0 qfile -o | more
which says I don't have a single orphan on my machine.
Here /usr/lib is a symlink to /usr/lib64

Now that you mention it: /usr/lib is supposed to be a symlink to
/usr/lib64 on my workstation too (like it is on all my other machines).
But it's not. Seems like something went wrong during installation. Maybe
a bad stage3 image. I created the symlink manually and now emerge -e world.

Hi,
I haven't tried Neil's method so I cannot comment on that.
Personally I actually start with
revdep-rebuild -ip
to see if anything is flagged. If there is then I run
equery depends whatever-was-found
and
equery belongs whatever-was-found
to see what uses (if anything) and what owns (if anything)
whatever-was-found. If nothing uses or owns then I delete it by hand.
It's labor intensive. Possibly Neil's metthod gets around some of
that. However I've used this for years and seldom had too many things
to clean up, and what I have had wasn't too difficult to work though.
There were some issue with Flash on one of my machine last week that
took awhile to dig through.
I try to do my machine once every couple of months.
HTH,
Mark
