Hi, Eric. I'm using the packages provided by Fedora:
numpy.x86_64 1.2.0-1.fc9
python-matplotlib.x86_64 0.91.4-1.fc9
It appears that numpy is reasonably up-to-date, but Matplotlib appears
to be relatively old (although I don't know what d(version)/dt is).
I'll look into installing from the source kits (and/or look into Fedora
10, which will be shipping in a couple of weeks, IIRC).
Thanks.
- Mike
