I have a program with an embedded copy of ffmpeg that is choking on a lack of libva-glx.so.2.

Debian has it in a libva-glx package.
Manjaro has it in their general libva package.

On Gentoo there is no trace of it…  At least not until I use the ‘ebuild’ tool to build the libva package manually and sic ‘find’ on the compilation results.

Then I find /var/tmp/portage/media-libs/libva-2.19.0/work/libva-2.19.0/va/.libs/libva-glx.so.2

So…  apparently it builds the glx support libraries in a *hidden* folder?  And I’m guessing then the ebuild’s install phase fails to spot it? 

I’m thinking this is probably worthy of a bug report, but I want to make sure there’s not some reason why these libraries are being left out on purpose first.  Other distros have them, and I see at least one bug report about Steam now requiring it, so it probably needs sorting out somehow…
