I'm sorry this is so frustrating -- it is certainly frustrating for
me. The problem is that matplotlib is trying to support three array
packages (Numeric, numarray and numpy) and numpy itself is a fast
moving target so if you don't have exactly the right numpy with
exactly the right scipy with exactly the right matplotlib it is
unlikely to work.

I suggest either the latest release of all three, or the latest svn of
all three. I notice from your output that you have 0.87.3 which is
several releases behind. Try getting numpy 1.0 and matplotlib 0.87.7.

Good luck!

Windows users have to watch out: the current Scipy binary installer is out of sync with the current Numpy installer.
(I think the Scipy people are going to fix that soon. In the meantime, I have a matched set of Numpy and Scipy installers for Windows and Python 2.4.3 that works with the latest mpl binary installer. I'm happy to provide my installers if anyone wants them. Contact me directly.)

This is just to let you know that I fixed the plot problem by installing the newest Matplotlib (0.87.7) and creating ~/.matplotlib/matplotlibrc. Adam, John and Gary, thank you very much!
