GotoBLAS will speed up linear algebra computation with NumPy and SciPy, 
and it is trivial to build. The catch is that GotoBLAS is only free for 
personal or academic use.
 
Note that most use of NumPy or SciPy do not involve heavy use of LAPACK, 
and the computational bottleneck tends to be in the creation of 
temporary arrays, not in CPU-intensive computation.
