Comment # 4 on bug 94037 from peter.fiss@gmx.de

I needed to install llvm-svn, because it was a dependency of mesa-git from the
Arch User Repository. As a non-mesa-dev this seemed to be the easiest way for
me to get mesa-git to work.

Anyway, I can confirm that the bug is fixed in mesa-git. Thanks for your help
and for the excellent response time!
