[Matplotlib-users] Fwd: Matplotlib backend issue

[Tommy G. <tg...@ma...>]

I just installed matplotlib on a new MacBook Pro

ActivePython 2.7.2.5 (ActiveState Software Inc.) based on
Python 2.7.2 (default, Jun 24 2011, 12:20:15) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> numpy.__version__
'1.7.1'
>>> import matplotlib
>>> matplotlib.__version__
'1.2.1'
>>> matplotlib.matplotlib_fname()
'/Users/tgrav/.matplotlib/matplotlibrc'
>>> 

That works fine. However, when I try to do

import matplotlib.pyplot as plt

it tries to open X11, which I have not installed and would like to 
try to avoid. The matplotlibrc file has

backend     : MacOSX 

Anyone know why it is still trying to open X11 and how I can avoid that?
