The demo doesn't work out of the box. You need to install download the 
freefont fonts into your mpl-data directory, and then add the following 
before the pylab import in mathtext2_demo.py:

from matplotlib import rcParams
rcParams['mathtext2'] = True
rcParams['mathtext.rm'] = 'FreeSerif.ttf'
rcParams['mathtext.it'] = 'FreeSerifItalic.ttf'
rcParams['mathtext.tt'] = 'FreeMono.ttf'
rcParams['mathtext.mit'] = 'FreeSerifItalic.ttf'
rcParams['mathtext.cal'] = 'FreeSansOblique.ttf'
rcParams['mathtext.nonascii'] = 'FreeSerif.ttf'

It=C5=9B working now, thanks. Just a remark why the fonts must be in mpl-da=
ta and=20
why matplotlib is not using the fonts who are in the system?=20

N.

It's a bug. Edin said he would work on it.
