I've just rebuilt these wheels with the just-released OpenBLAS 0.2.18.

OpenBLAS is now passing all its own tests and tests on numpy / scipy /
scikit-learn at http://build.openblas.net/builders

Our tests of the wheels look good too:

https://travis-ci.org/matthew-brett/manylinux-testing

So I think these are ready to go.  I propose uploading these wheels
for numpy and scipy to pypi tomorrow unless anyone has an objection.

Cheers,

Matthew
