llvm < 3.4 is specified for the llvm use flag in mesa. So I turned off
that flag.

That does explain things.

Llvm is used for the gallium part of mesa. So won't this require
excluding the gallium use flag as well?

I don't use high-end graphics on my system but I recall that some
time ago I had problems with other stuff if I omitted the gallium
and llvm use flags on mesa. Otherwise I'd eliminate gallium entirely.
At that time, I didn't question the reason because I didn't need to know
and I didn't really care as long as everything worked.

This condition can only be temporary as future releases of mesa
will likely use llvm >= 3.4. Since on my system llvm is not used for
anything else other than mesa gallum, I'll just leave things as they are.

I don’t know. I updated LLVM so I could maintain my Pure language
ebuilds. Otherwise I am not a big fan of clang and so forth.
