------------------------+--------------------------------
 I am using MacPorts on OS X 10.8 (Mountain Lion) and XCode 4.6.1. I am
 encountering problems with matplotlib and I have not found any solution
 browsing existing bug reports and the internet. Maybe there is someone
 around who can help...

 I installed py27-matplotlib without any compilation error. However when
 trying to import matplotlib.pyplot in ipython (also installed via
 macports) I get the following error:

 {{{
 In [1]: import matplotlib.pyplot as plt

 I get the same error using the normal macports python. I also get the same
 error message trying to import Tkinter in python/ipython.

 Anybody having an idea what's going on?
