python.org python installs into /Library/Frameworks/Python.framework
and its main site-packages directory is the line listed above.
That is where *all* packages get installed by default (e.g. by distutils 
or pip).
I suspect the original poster has a conflict with another version of 
python or another package management system such as homebrew. You can 
verify which python is running using "which python" (it should be 
/usr/local/bin/python, which is a symlink to a binary in 
/Library/Frameworks/Python.framework,
or the actual binary itself, depending on your $PATH.
One can test matplotlib using:
python -c "import matplotlib as m ; m.test(verbosity=1)"
If that works then I suspect ipython is misinstalled.

I should have said: 'Consider the _results_ of the following script:' I originally tried to attach the results I obtained, which showed no change in color for the markers in the legend, while the line connecting the markers in the legend did change color.
Actualy your question is correctly posted but I misread it. Calling
set_color changes only the line color, not the markers. This is
expected and documented behavoir. There are separate methods for the
markers:
line[0].set_markerfacecolor
line[0].set_markeredgecolor
See http://matplotlib.sourceforge.net/api/artist_api.html#matplotlib.lines.Line2D

To avoid (not so) rude answer like Mark's one, please try first to refer
to:
- the documentation of the pyplot's commands you use
http://matplotlib.sourceforge.net/api/pyplot_api.html
It tries (pretty well IMHO) to be comprehensive, at least for 99% of use
cases,
- you can set, once for all, the properties of most matplotlib objects
in the configuration file. An example is here:
http://matplotlib.sourceforge.net/users/customizing.html#a-sample-matplotlibrc-file 
It may be a good starting point to determine the name of the property
you are looking for.
Regards,

Actually I had some problems to find the solution on the web.
Finally I've used: matplotlib.rcParams['legend.fontsize'] = 25.0 and it
works well

I don't wish to appear rude as this list is associated with the Python 
language, but do you ever try a search engine before you ask a question?

Hello Fabien,
There is a font size attribute to ``legend``. Here is the description from
the docstring:
 *fontsize*: [ size in points | 'xx-small' | 'x-small' |
 'small' | 'medium' | 'large' | 'x-large' | 'xx-large' ]
 Set the font size. May be either a size string, relative to
 the default font size, or an absolute font size in points. This
 argument is only used if prop is not specified.
Cheers,
Nelle

Hello,
The question is in the title :)
Cheers!
Fabien

Hi,
I think I was tired yesterday.
matplotlib.rcParams['xtick.labelsize'] = 20.0 works perfectly also
with xlabel("name", size= 30)
Thanks all,
Fabien

Did you ever find the cause of this?
I found that the get_py2exe_datafiles() method didn't find those fonts but
even when I got the fonts manually I still had the same issue with
matplotlib's Font Manager not being able to find them.
