Apparently upstream no longer makes rpi-gles optional. Because I'm not a programmer, I don't know if this means upstream now unconditionally inclues support for rpi-gles or if rpi-gles is deprecated. All of my amd64 and x86 PCs failed mpv-9999 with this message.

Same issue for me. Thanks
After inspecting the patch provided in bug# 534018 and the npv-9999.ebuild, I was able to determine the only mention of 'rpi-gles' was this line: $(use_enable raspberry-pi rpi-gles) As a temporary work-around, I removed said line and executed: ebuild /usr/portage/media-video/mpv/mpv-9999.ebuild manifest && emerge =media-video/mpv-9999 If I have a need to modify an ebuild or test a potential patch, I normally copy the requisite package directory from /usr/portage/ to /usr/local/portage. However, in this instance, I felt I didn't need to worry about 'losing' the above change on my next emaint sync. As a matter of course, I don't recommend changing ebuilds under /usr/portage. This is purely a temporary work-around.
I already merged a PR with a fix couple of days ago, see: https://gitweb.gentoo.org/repo/gentoo.git/commit/media-video/mpv?id=18df1b3978848f1f209f207954c8a3d72c0753c6 Closing report.
