[IPython-User] Trouble with matplotlib fonts in IPython notebook

[Mike Witt]

I've just begun trying to use the IPython notebook, and I'm having
a problem with the example file: 00_notebook_tour. Any of the examples
that use latex on a matplotlib plot (for instance, the very last example
in the tour notebook) give me a bunch of errors apparently from the
matplotlib "font manager" (I've used matplotlib with Sage, but I don't
really know a lot about it.)

I imagine that I simply don't have the necessary fonts installed, or
else something needs to be configured to identify where the fonts are?
I using:

   Fedora 16
   python 2.7.2
   IPython 0.13.dev (from a couple of days ago)

I'll include the errors at the end.

Thanks!
