I don't know if lives requires sox, but the ebuild shows a requirement with a minimum version, and then later a requirement depending on the sox use flag: DEPEND=">=media-video/mplayer-0.90-r2 >=media-gfx/imagemagick-5.5.6 >=dev-lang/perl-5.8.0-r12 >=x11-libs/gtk+-2.2.1 media-libs/libsdl >=media-video/ffmpeg-0.4.8 >=media-libs/jpeg-6b-r3 >=media-sound/sox-12.17.3-r3 xmms? ( >=media-sound/xmms-1.2.7-r20 ) virtual/cdrtools theora? ( media-libs/libtheora ) >=dev-lang/python-2.3.4 matroska? ( media-video/mkvtoolnix media-libs/libmatroska ) ogg? ( media-sound/ogmtools ) >=media-video/mjpegtools-1.6.2 libvisual? ( =media-libs/libvisual-0.2* ) media-sound/jack-audio-connection-kit sox? ( media-sound/sox )"
What's the point of the flag at all?
I went ahead and removed the flag since I couldn't find any reason for having it and the bug has just been sitting around for ages now :)
