preserved-rebuild, avidemux and mplayer

Hi,

I'm in the middle of a world update. I'm sort of doing it in parts
because of the device-mapper issue. Anyway, I keep getting the
@preserved-rebuild at the end of the emerge. I run it and it wants to
run it again. When I run it again, it wants to run it again. It's the
same packages over and over again. This is the outputs:

!!! existing preserved libs:
>>> package: media-libs/x264-0.0.20091021
* - /usr/lib/libx264.so.65
* used by /usr/bin/avidemux2_cli (media-video/avidemux-2.4.4-r2)
* used by /usr/bin/avidemux2_gtk (media-video/avidemux-2.4.4-r2)
* used by /usr/bin/avidemux2_qt4 (media-video/avidemux-2.4.4-r2)
* used by 2 other files
Use emerge @preserved-rebuild to rebuild packages using these libraries

and

and this just repeats. Those are in reverse order by the way.

I'm not a magician but I need a magic trick.

Thanks.

Abracadabra... rm /var/lib/portage/preserved_libs_registry

Be sure to have emerged the @preserved-rebuild stuff at least once, then
you are safe.

Most likely avidemux and mplayer have hidden automagic dependencies on x264
but they are not listed in DEPEND. So the packages need x264 but portage
doesn't know this.

Try unmerge the whole lot and re-merge everything. This should un-confuse
portage. Or you can fire out your trusty vi and fiddle with the contents of
/var/lib/portage/preserved_libs_registry

If you have time and inclination, you can run ldd on each file listed in the
"used by" lines and search for "not found". Eyeballs should reveal what is
going on.

Unmerging then emerging again fixed it. Is this a bug or just a one
time boo boo?

No, it's pretty consistent. It's also not something that portage can do
anything about as the information on disk conflicts with what is in portage's
database.

The ebuilds have bugs and should be reported as such - there is missing
information in DEPEND

Well, it's back. I'm going to call this "unmasking creep". I had to
unmask and keyword some stuff until portage was happy to install the
updates.
I had to add the following to package.unmask and package.keyword:

=media-video/mplayer-1.0_rc4_p20091026-r1
=media-libs/x264-0.0.20091021
media-video/ffmpeg
media-video/avidemux

Maybe this will help someone else if they run into this "issue".
