David,
   I suspect you might be running into problem with...

CMAKE_OPTIONS="-DLLVM_BUILD_32_BITS:BOOL=ON -DLLVM_TARGETS_TO_BUILD=PowerPC"

not working properly in the llvm 2.9 release for building with cmake.

If you can tolerate the complete build by changing this to...

CMAKE_OPTIONS="-DLLVM_BUILD_32_BITS:BOOL=ON"

then llvm 2.9 should build on powerpc-apple-darwin8. This issue shouldn't exist for
i386-apple-darwin8.
