I upgraded to Fedora Core 3 and hence spent some time rebuiding all of
the Python modules I use frequently...
In order to compile matplotlib, I had to install pycxx as a separate
package. I noticed that there was a cxx directory in the matplotlib
tree, but it didn't seem to be using it.
I got it to compile and it seems to be working. This message is just
for someone's information to point out the dependency, or the fact
that the stuff in the cxx directory doesn't seem to be satisfying it.
