There's nothing default about it. You should use the [lapack_opt] section to specify whichever BLAS and LAPACK libraries you like, even if they are not optimized. > > > 2) Also, my main Python directory is called Python-2.5.2.

Can you just do a "python setup.py install" instead of going through the menu system?
