The new port of LLVM (3.7.1 as currently present in ports)
comes a much longer way to actually building on macppc.
However, it eventually fails with
# make
===> Building for llvm-3.7.1p0

Indeed, the symbols __dso_handle and __guard_local defined
in libclang.so.2.0 are also defined in /usr/lib/crtbegin.o
Is this a powerpc specific problem?
It builds fine on amd64.
