Thanks for the response. Numpy/SciPy has always been one of the most
difficult packages to install I've ever encountered (I've installed
hundreds of tarballs over the years). I've been using SUSE since version
6.4, and it's always a battle to get Numpy/SciPy running. I succeed
about every other release, but only after many hours of work. Half the
time I fail and don't use Numpy/SciPy until the next release. By then
I've forgotten the incredible frustration, and try again.

I tried to install from source with this result:

deserv:/usr/local/src/numpy-1.0.3 # python setup.py install
Running from numpy source directory.
Traceback (most recent call last):
  File "setup.py", line 91, in <module>

    raise DistutilsPlatformError(my_msg)
distutils.errors.DistutilsPlatformError: invalid Python installation: unable to open /usr/lib/python2.5/config/Makefile (No such file or
+directory)

There is no 'config' directory under /usr/lib/python2.5

There is a science repository linked from http://www.scipy.org/Installing_SciPy/Linux

http://repos.opensuse.org/science/

I tried to install from the RPMs there, but the recursive dependency
chain broke when a gfortran lib that isn't there was required. I also
wonder if there was ANY testing by the packagers.

Times out. :( 

Again, thanks for the response. I think I'm going to go do something
more pleasant, like lay on a stinging ant nest...
