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.
