Description

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
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

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?

Hmmm, I can import both just fine. Maybe do a port -v selfupdate && port -v upgrade outdated?

There are several old references to the same issue with different ports both in Trac and mailing lists' archive, try checking those.
