OpenMP is tricky under MacOSX: 10.7-10.9 had no support at all (they
use clang <3.6). Since 10.10, the support is incomplete, well at least
many code I tested fail with OpenMP (they run under linux and windows),
I noticed wrong results, not only failure to compile !

Of course on can install gcc or icc, but this is not in Python's philosophy
