[SciPy-dev] Seg fault while running scipy.test under Red Hat EL

I have just installed numpy and scipy from the svn repository and I am
having a few problems.  I get a seg. fault when I run scipy.test(1,10) (see
results below).  And I get the following error when I try to load the stats
package:

$ python2.5

    from scipy.linalg import fblas

I am using RedHat Enterprise Linux with gcc and g77 version 3.4.6.



Can someone help me understand what is wrong with my installation and how to
fix it?

Thanks,
Jeremy
