My armv6 context has a clang based buildworld and buildkernel. My powerpc kernel builds have a gcc 4.2.1 based buildkernel (no buildworld). > > I've not seen the problem for amd64 targeting amd64 via clang as far as I can remember.

It was a temporary workaround until bmake was fixed. -- Regards, Bryan Drewery
