*DO NOT* add the USE flag "doc" into you /etc/make.conf, That may cause
many unexpected conflict. Somebody had told me this several years
before.
If you need doc for any package, just add this flag int file
/etc/portage/package.use for the certain package.

That's exactly what I've done. I do *not* have 'doc' in make.conf, I
have it in package.use for a handful of packages.

Atandard documentation: READMEs, manpages, info pages, is installed by
default. The doc flag enables extra documentation for developers. This
often needs to be built from the sources, and thus requires extra tools.
These often cause blocks, however, it does not appear that the doc flag
is at fault here. You have changed other flags, such as ipv6, so the
advice is to make such sweeping USE flag changes one at a time. This
often avoids the problem and otherwise makes it easier to see.
the output you posted is hard to read because your mailer wrapped it but
it may be that updating sysvinit manually first will clear it.

Point taken, thanks.

It did it indeed, so the immediate problem is solved, thanks a lot for
that.
However, I'd be obliged if you could tell me what was wrong and why an
update cleared it? I genuinely don't understand what goes on and I'd be
keen to learn about how Gentoo manages dependencies.
Thanks,
Zoltan

To be honest, it was a bit of a guess, because I had so much trouble
parsing the wrapped emerge output. The basic problem is that you have a
package that portage wants to update, but another package wants to keep
it at the same version. This is generally solved by either updating
individual packages manually or unmerging the package causing the
problem and then letting portage pull in the correct versions.
In most cases, portage can now handle these things automatically but
there are time it cannot. This may well have been caused by the various
USE flag changes in your situation. If you make massive changes to your
USE flags after installing from a stage 3, you can often see this sort of
behaviour. The solution is generally to take small steps, change a few
flags at a time.

Hi Zoltan,
if you run into issues like this, first try something like
emerge -uDNav world
(--update --deep --newuse --ask --verbose; note the "deep")
(afaik this is the recommended way to update your system anyway)
If this doesnt help, you can try giving portage more time to backtrack, add
e.g. the following option (warning this may take a while):
--backtrack=1000
Cheers, Andreas

Thanks, will do that.
Is there a comprehensive manual about portage and the related tools?
I mean one which explains how the whole thing works, what are atoms and
sets and slots and masks; how dependencies work and how the magic USE
keywords get translated to actual configure parameters, so basically
the whole logic behind it? Then, with all that basic knowledge how
emerge et al work on that info and what they actually do?
As a developer probably it's all obvious if not trivial to you, but to
the uninitiated it looks a bit of black magic. I went to the Wiki and
went through the handbook, but I couldn't find anything which explained
the actual concepts and implementation of the whole portage system,
just practical snippets of actual tool usage rather than the
foundations. Any pointers to the relevant literature would be most
appreciated.
Thanks,
Zoltan

Portage man pages are fairly complete (maybe not so much for very new
features). The trick is to find the man pages :-)
equery files portage | grep /man/
These are the man pages I rate most useful (there are plenty more)
emerge(1)
portage(5)
ebuild(1)
ebuild(5)
