The current version of NumPy (17.0) can be compiled to use other BLAS
and LAPACK libraries.

The last time I compiled ATLAS it took a *long* time, which is a
reason I can see for not including it with the NumPy distribution.

Mind you, since the BLAS routines for matrix multiplication aren't
used, it wouldn't speed that up.
