I have built packages for Scientific Python (http://www.scipy.org/) for
SL 3.0.4
Also, I made some useful companions such matplotlib, gnuplot-py and
numarray (rebuilt for use with ATLAS).
It's not perfect yet, as you'll need numeric (easily obtanained from
dag repository, and install pylab.py in /usr/lib/python2.2/site-packages/
in a manual way (solved in python2.3). You will also need to deinstall
lapack and blas, as it conflicts with ATLAS.
You can get them at
