I'm attempting to bootstrap clang-3.0 on powerpc-darwin8.
Stage 1 built with g++-4.0.1 ok, a few test failures with details found at:
http://www.csl.cornell.edu/~fang/sw/llvm/logs/llvm-clang-release-3.0-patched-1-powerpc-darwin8-g++-4.0.1-fink-build-log.txt
(+ .bz2 for compressed)

at stage 2, building with stage-1-built clang:
