Yes, I did that. Some Googling found the correct way to do it:

python3.2
>>> import matplotlib
>>> matplotlib.test()
..K........./usr/lib/python3/dist-packages/nose/tools.py:82:
ResourceWarning: unclosed file <_io.BufferedRandom name=3>
   pass
...../usr/lib/python3.2/subprocess.py:650: ResourceWarning: unclosed file
<_io.FileIO name=6 mode='rb'>
   _cleanup()
/usr/lib/python3.2/subprocess.py:650: ResourceWarning: unclosed file
<_io.FileIO name=8 mode='rb'>
   _cleanup()

Many "."s and "K"s are output.

The K's are probably because some requirement of the test framework (ghostscript or inkscape) is not being found on your machine.

This is a new test as of yesterday. Can you add a print to figure out what afm.string_width_height() returns? I'm curious as to what way this is failing on your machine.
