Re: [Matplotlib-users] Py2app application with matplotlib fails on OS X 10.6

[Emanuele S. <ema...@gm...>]

We saw the same problem with VisTrails (www.vistrails.org).

It seems that python.org's python can't build the fonts in  
~/.matplotlib on snow leopard.
We noticed that importing matplotlib.axis using Apple's python will do  
that.

So this is the work-around we found for vistrails (bundled with python.org 
  2.5)

In a terminal on snow leopard:

$ rm -rf ~/.matplotlib
$ cd /Applications/Vistrails.app/Contents/Resources/lib/python2.5
$ DYLD_LIBRARY_PATH=/usr/lib  /System/Library/Frameworks/ 
Python.framework/Versions/2.5/bin/python

 >>> import matplotlib.axis

Now running the app again works.

The DYLD_LIBRARY_PATH is necessary because of problems we saw with  
different versions of libgcc_s.1.dylib present in the system and the  
wrong one was being loaded.

I don't think it's a py2app bug because I can reproduce it by just  
running python.org's python and importing matplotlib.axis.

I guess it is a bug in matplotlib.
