Also ebuild automagically dependends on drm backend of libva, i.e. x11-libs/libva[drm] and implies dependency on external media-libs/libvpx, but passes --enable-builtin-libvpx=no, with this option external libvpx isn't used and has use flags such as opengl, but unconditionally pulls this dependencies even if they're disabled So, in short: --- a/gst-plugins-vaapi-0.5.10.ebuild 2015-03-30 16:06:40.000000000 +0300 +++ b/gst-plugins-vaapi-0.5.10.ebuild 2015-08-06 04:51:17.000000000 +0300 @@ -13,20 +13,27 @@ LICENSE="LGPL-2.1" SLOT="1.0" KEYWORDS="~amd64" -IUSE="+X opengl wayland" +IUSE="drm +X opengl wayland" RDEPEND=" >=dev-libs/glib-2.34.3:2[${MULTILIB_USEDEP}] - media-libs/libvpx[${MULTILIB_USEDEP}] >=media-libs/gstreamer-1.2.3:1.0[${MULTILIB_USEDEP}] >=media-libs/gst-plugins-base-1.2.3:1.0[${MULTILIB_USEDEP}] >=media-libs/gst-plugins-bad-1.2.3:1.0[${MULTILIB_USEDEP}] - >=x11-libs/libdrm-2.4.46[${MULTILIB_USEDEP}] - >=x11-libs/libX11-1.6.2[${MULTILIB_USEDEP}] - >=x11-libs/libXrandr-1.4.2[${MULTILIB_USEDEP}] - >=x11-libs/libva-1.4.0[X?,opengl?,wayland?,${MULTILIB_USEDEP}] - >=virtual/opengl-7.0-r1[${MULTILIB_USEDEP}] - >=virtual/libudev-208:=[${MULTILIB_USEDEP}] + drm?
