[Numpy-discussion] OpenBLAS on Mac

Indeed I just ran the bench on my Mac and OSX Veclib is more than 2x
faster than OpenBLAS on such squared matrix multiplication (I just
have 2 physical cores on this box).
MKL from Canopy Express is slightly slower OpenBLAS for this GEMM
bench on that box.
I really wonder why Veclib is faster in this case. Maybe OSX 10.9 did
improve its perf...
