somewhat older test wheels for python-2.7 can be downloaded here:
see:
http://figshare.com/articles/search?q=numpy&quick=1&x=0&y=0 (2014-06-10) numpy and scipy wheels for py-2.7
The scipy test suite (amd64) emits segfaults with multithreaded OpenBLAS, but is stable with single thread (see the log files). I didn't dig into this further. Win32 works with MT OpenBLAS, but has some test failures with atan2 and hypot. The is more or less the status today. I can upload new wheels linked against a recent OpenBLAS, maybe tomorrow on Binstar.
