llvm-amdgpu-svn (1) & lib32-llvm-amdgpu-svn (2) were needed to build mesa-git master versions. llvm 3.3 is now in the official repos and built with amdgpu / R600 enabled and mesa-git master builds fine against that version, so these 2 packages are no longer needed.
Please delete (1) and (2) . (1) https://aur.archlinux.org/packages/llvm-amdgpu-svn/ (2) https://aur.archlinux.org/packages/lib32-llvm-amdgpu-svn/
