We certainly can't help without more information: we need information
like platform (OS), compiler, BLAS/LAPACK (and how it was built if it
was), eventually CPU.

There should be an easy way to produce those data, directly from scipy,
though, because it is difficult for users to know what's relevant.
Something like scipy.build_info module, or whatever.
