All the ebuilds for media-libs/libvpx only list a dependency on yasm per ABI, and x32 is not listed as one of them. This causes a build failure on x32: /bin/sh: yasm: command not found See https://bugs.gentoo.org/attachment.cgi?id=426398 for the full build failure log. The ebuilds should include the DEPEND line: abi_x86_x32? ( dev-lang/yasm )
