Thanks for the report!

This is, in part, due to the automagic detection of SWIG and LuaJIT, and the ebuild not yet handling them.

That said, having installed SWIG and LuaJIT here, the build is a success, so I'm not sure at this time what is going wrong there (or rather why it's doing so).

What version(s) of SWIG and LuaJIT do you have installed?  I'm not too optimistic about that making a difference, and I already tried several combinations locally.

I see that you have 'ACCEPT_KEYWORDS="amd64"', but you also have a bunch of packages from '~amd64'.  Mixing 'stable' with 'unstable' is usually not a good idea.  :]

As a quick workaround, to get OBS Studio going, you could uninstall 'dev-lang/swig' for the duration of the configure/build.

Actually, updating LuaJIT to 2.0.5 and re-emerging SWIG solved the issue.
