As far as I can see, there will be some minimal backport for Python 2.7.

You could try this approach first (i.e. set some environment variables
to point distutils to clang):

http://bugs.python.org/issue13590#msg152803

If that fails, I'd suggest to try a fresh Python compiled from source
with the tools you have in your Xcode version.
