SSIA i've reported that llvm-3.0-PPC_macro.patch is required for sys-devel/llvm-9999 in bug #403519 and voyageur already fixed. this fix is also required to emerge sys-devel/clang on ~ppc. IMHO, clang and llvm are very experimental and their release quality is extremely low, especially for minor arch, such as ppc. if the maintainer doesn't mind, it would be good to add epatch_user to make ease bombing/testing patches to/for upstream via gentoo's emerge technology.

Indeed, grobian tried to get it working in bug #405147, but it was indeed limited. Also it is sad to see the upstream bug on this patch has not progressed: http://llvm.org/bugs/show_bug.cgi?id=10969 I'll see which is best between using base eclass or simply adding epatch_user call so you can test it easily
Let's keep changes simple, I added a call to epatch_user in 3.0-r3 and 9999 ebuilds. Thanks for the report and enjoy! I will add them to llvm ebuilds too
