[Numpy-discussion] Strange crash in numpy.linalg.lstsq.

Right... So I was able to get everything working finally. I am not
100% sure how or why it works though so I am going to outline what I
did here for reference.
I first tried just using LAPACK 3.1.1 (since it seemed set up for g77
instead of gfortran which I do not have). I compiled this to yield
the associated lapack and blas libraries using the fortran compiler
settings detailed on the scipy install web page. This actually gave
me a numpy with the same problems (hanging on numpy.test()). Thus I
realized the problem was LAPACK and not with ATLAS.
Eventually I got numpy with LAPACK to work when I used the default
settings in the example config file of LAPACK instead of using the
suggested settings on the numpy web site. I then compiled ATLAS and
this worked as well. It still seems a little bit weird that these
settings can break the software though.
Thanks for the suggestions and I hope this helps someone.
Jonathan.
