Hi Michael,
I put in the rc line you suggested below into fonts_demo.py but didn't see it
print any extra info (but did confirm in ipython that rcParams showed
verbose.level had changed to "annoying"). It just quietly finished otherwise.
Did I miss something here?
I've linked the output of fonts_demo.py to;

If I need to upgrade matplotlib above 0.90.1 I guess I'll have to build it
separately unfortunately. We're trying to stick to the standard ubuntu
packages that get pulled in for that release.
Thanks for your help,
Paul
