With Tk-Cocoa, typically you see this message when mixing libraries that 
are linked to the system Tk in /System/Library/Frameworks/Tk.framework 
and another installation (typically ActiveTcl) in 
/Library/Frameworks/Tk.framework. OS X gets confused and crashes with 
that error message.

The only solution I've found is by making sure that all of your 
Tk-linked libraries link to one location or the other. You can do this 
by running otool -L on the relevant binaries and seeing where things are 
linked. If you're only seeing this issue now after building matplotlib, 
then it's logical to assume that matplotlib may have been linked to the 
wrong library. You can change the linking by running install_name_tool 
to get matplotlib to point to the correct version of Tk.
