Hi all,

It would be very helpful, if some information would be available at a c

e.g. http://www.scipy.org/documentation/buildatlas4scipy.txt
(instead of scanning mailing lists ;-) )

g77  -funroll-all-loops -O3 -m64 -fno-second-underscore -fPIC -c *.f

ranlib libfblas.a

to build the BLAS library.

NOOPT    = -m64 -fno-second-underscore -fPIC

Some information on ATLAS should be added as well. So far I have only
