As the title says media-video/libav-9999[truetype] pulls in media-libs/truetype which does not exist and to my knowledge cannot exist as to my knowledge the only TrueType implementation for *nix is known as freetype. Reproducible: Always Steps to Reproduce: USE=truetype emerge -pv =media-video/libav-9999 Actual Results: media-video/libav:0 emerge: there are no ebuilds to satisfy "media-libs/truetype". (dependency required by "media-video/libav-9999[truetype]" [ebuild]) Expected Results: Just a guess but it should probably depend on media-libs/freetype instead.
