Uh, the "other package" he's talking about is GCC. Good luck with that.

I still think you need to make Clang use its internal headers instead of
GCC's internal headers. That was the original problem here. You should
probably get rid of the -I parameter adding GCC's internal headers to
Clang's search path. If that doesn't work, put it back, then try adding
a '-I/usr/lib/clang/2.9/include' to the command line.
