Congratulations!  As a long-ago HP-UX user I know how hard it can be to 
get some freeware working on it.  Do you know of the archive at

I believe that the INSTALL.txt file which comes with scipy is out of 
date compared with the scipy.org online documentation.  See 
http://www.scipy.org/documentation/buildscipy.txt.  You should be able 
to simply say

python setup.py build --fcompiler=hpux

(although the comment at the top says --compiler=hpux).

This looks like a big-endian vs. little-endian hardware issue to me.

Hmm...locally I've built scipy with the libraries and includes in either 
/usr/lib/atlas and /usr/include atlas or /usr/local/lib/atlas and 
/usr/local/include/atlas. scipy seems to find them when they're in 
either place without me having to do anything special.
