We've uploaded a snapshot with the fix to our server. Could you
give it a try ?


This is a source archive, so you'll have to do the usual
"python setup.py install" dance to get it installed.

The fix we've applied will test the compiler setup and try clang
in case it cannot find the compiler with which Python itself
was compiled. It should work with all supported Python versions
(not only Python 2.7.3 which includes the distutils fix).
