I use up-to-date Debian testing (wheezy) with the amd64 architecture
and Debian's python3.2. I install matplotlib from the tarball
matplotlib-matplotlib-v1.1.0-684-ge87374e.tar.gz
Before the current install, I had also on my system Debian's
python-matplotlib and python-matplotlib-data packages. They contain
some of the same
files as the tarball (/etc/matplotlibrc). I have completely removed the two
Debian packages. My Debian system includes the packages python3-tk, tck8.5,
tcl8.5-dev, tk8.5, and tk-dev.
I did a new matplotlib install, starting by unpacking the tarball.
In /usr/local/lib/python3.2/dist-packages/matplotlib/tests/test_text.py
in test_afm_kerning, I added before the assert:
xxx = afm.string_width_height('VAVAVAVAVAVA')
print(xxx)
The results are:

Here is one of matplotlib's simple sample programs. It works.
#! /usr/bin/env python3.2
from pylab import *
t = arange(0.0, 2.0, 0.01)
s = sin(2*pi*t)
plot(t, s, linewidth=1.0)
