Portage incorrectly solve this dependencies: " || ( media-libs/libpostproc <media-video/libav-0.8.2-r1 media-video/ffmpeg ) >=virtual/ffmpeg-0.10.2 " which i.e. can be found in media-video/mplayer2-2.0_p20120309 and media-plugins/gst-plugins-ffmpeg-0.10.13-r2 Reproducible: Always Steps to Reproduce: 1. Have almost stable fully updated system (amd64) with media-video/libav and mplayer2 and/or gst-plugins-ffmpeg installed 2.
