I've been trying to emerge -u world, but getting this block...
| Code: |
# emerge -uUD world --backtrack=100 --with-bdeps=y && emerge @preserved-rebuild
Calculating dependencies... done!

!!! Multiple package instances within a single package slot have been pulled

^^^^^^^^
(and 4 more with the same problem)
It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.
For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

What is going on? If ffmpeg and libav are supposed to block each other, why is the virtual package for ffmpeg pulling in libav? Is there some configuration option that I'm missing? In this case, I have no preference for ffmpeg or libav, I would just like to get my system in working state. The a/v programs I want to use are openshot, vlc, and pianobar.
Is it just a case of "wait a bit for the ebuild maintainers to fix it?" If so, I'm cool with that.
Thanks so much!

Possible you may need to enable (or disable) some useflags on media-video/ffmpeg. It may help to add media-video/libav to your package.mask. The virtual may be pulling libav because something in the installed version of ffmpeg does not satisfy the dependencies.

@yngwin
for us normal users any emerge output looks strange and complex in our eyes (altough it really is not). I would advise to update the @world to at least the most recent stable before doing any further USE changes. And of course any "eselect news read" available .... |

/me wonders if | Code: | | [ebuild UD#] dev-lang/perl-5.18.2-r2 [5.20.2] |
is just an artefact of the back switch to libav->ffmpeg or a separate issue ? |

I had tried "-libav" (as hinted at in the news), but it didn't help. Masking libav did the trick and I am now emerging @world, thanks! |
