Hi Edin, I am not able to run the example when I have freefont installed in /usr/local/share/fonts (although they are accessible by other programs, so they are installed properly as far as X is concerned), but if I copy the ttf's to the fonts directory in matplotlib's source, and then python setup.py install, I am able to run your example, and have attached the resulting png. Note the line is missing in the 3/2 fraction.
