Great work so far, really looking forward to this release!

On OS X 10.8 here with `brew install python` and using gfortran 4.7.0 built from source with gfortran.
I compiled python and numpy with clang using latest Xcode.
Numpy tests all pass.

For scipy, I get quite a lot of these arpack symmetric_modes precision failures:

FAIL: test_arpack.test_symmetric_modes(True, <gen-symmetric>, 'd', 2, 'SA', None, 0.5, <function asarray at 0x10650be60>, None, 'buckling')

Not sure how severe that is.

Note: I had to add '-mno-avx' to numpy's extra_flags because '-march=native' lead gcc to spit out avx assembly code, which is not understood by Apple's assembler.
But that does not seem to be related, to the arpack mismatch issues.

The remaining 3 failues:
