I assume /usr/local/python/python-2.3-FC2/share/matplotlib exists and

Are you sure the rc file you are editing is being found and loaded.
Where are you placing the rc file?  The search order for rc is

     * current working dir
     * environ var MATPLOTLIBRC
     * HOME/.matplotlibrc
     * MATPLOTLIBDATA/.matplotlibrc

Yes, this is fixed in CVS, thanks.

Sorry for all your troubles.  There are a couple of additional hints
that may help you get your environment configured properly.  First,
run a test script, eg examples/simple_plot.py with the
--verbose-helpful flag.  This will give you information at runtime
about what resources matplotlib is loading, eg what data path
matplotlib is using, what rc file etc.

As indicated above, there are two additional things you can do to help
matplotlib find it's data files.  One, you can place an rc file in
your working directory if you don't want to use a home directory for
it.  Secondly, you can set the environment variable MATPLOTLIBDATA as
described at http://matplotlib.sourceforge.net/installing.html.

Hopefully with some combination of the extra ways to point matplotlib
to its data files and the extra diagnostic information from the
verbose flag, you can get this working.

Assuming /usr/local/python/python-2.3-FC2/share/matplotlib exists and
contains the files you referred to above, this is the dir that you
would set MATPLOTLIBDATA to point to.

If you find the magic combination, please post or for future googlers.
Or if you have any suggestions for documentation improvement let me
know.
