First, take a breath and try to relax. I know you're frustrated, but
being rude to the people you are asking help from isn't helping you get
your problems fixed.

Second, use scipy.test(verbosity=2) and give us the appropriate part of
the output (just the tail end before it crashes).

Third, you may also want to try the latest snapshot of the development
sources. 0.3.2 is quite old.

  http://ipython.scipy.org/tmp/scipy_cvs_2005-07-29.tgz

It's probably a problem with ATLAS since you are on an Athlon 64
processor and using Pentium-III binaries (and ATLAS is rather more
sensitive to the CPU than any other part of scipy). So fourth, you may
want to compile ATLAS from source, too. You can get the source package from

  http://math-atlas.sourceforge.net/

If you succeed in doing so, we would be interested in putting the
resulting binaries on the web site in order to save others using Athlon
64 chips the effort and frustration.
