I'll just mention that re-distribution of GotoBLAS is prohibited. So if
SciPy is to provide a BLAS superpack it will have to be ATLAS. That is
difficult as ATLAS requires more tuning parameters than GotoBLAS+LAPACK.
The performance of Intel's MKL and AMD's ACML is only slightly less than
GotoBLAS. If you cannot build NumPy with GotoBLAS and LAPACK, I suggest
you use MKL or ACML instead.
By the way, it would be better if NumPy and SciPy had a way of
replacing it's BLAS and LAPACK libraries. For example if they were not
statically linked, as today, they could be a DLL whose path would be
found in a config file.
