I think you right. OpenBLAS might even be a long-term solution. We should also consider that GotoBLAS (and GotoBLAS2) powered some of the World's most expensive superomputers for a decade. It is not like this is untested software. The remaining test errors on Windows are also due to MSVC and MinGW-w64 differences, not due to OpenBLAS itself, and those are not relevant on Linux. On Apple, I am not sure which is better. Accelerate is faster in some corner cases (level-1 BLAS with AVX, operations on very small matrices), but it has issues with multiprocessing (GCD's threadpool is not forksafe). Apart from that OpenBLAS and Accelerate are about equivalent in performance. I have built OpenBLAS on OSX with clang and gfortran, it works like a charm. So it might be worth cobsidering for binary wheels on OSX as well.
