import pylab - macosx 10.6

Hi Matplotlib Users,

First of all, I hope this is the right place to ask my questions, otherwise, apologies for the spam.

I am trying to install python on my mac (10.6.7) and I have some issues when trying to import pylab.
I installed python 2.7.1 from the EDP package (32-bit), I have numpy 1.5.0 and matplotlib 1.0.0.
I can import both numpy and matplotlib successfully (backend is MacOSX, I also tried TkAgg).

But no matter how I try to import pylab ("import pylab", "from pylab import *", "ipython -pylab", "from matplotlib import pylab") I always have the following message:

>>> import pylab
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/7.0/lib/python2.7/site-packages/pylab.py", line 1, in <module>

    from matplotlib import ft2font
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/7.0/lib/python2.7/site-packages/matplotlib/ft2font.so, 2): Library not loaded: @rpath/libfreetype.6.dylib
  Referenced from: /Library/Frameworks/Python.framework/Versions/7.0/lib/python2.7/site-packages/matplotlib/ft2font.so
  Reason: image not found

Just to be sure, a "which python" returns:

/Library/Frameworks/Python.framework/Versions/7.0/bin/python

I also checked that I do have the "ft2font.so" file inside /Library/Frameworks/Python.framework/Versions/7.0/lib/python2.7/site-packages/matplotlib/.

To me it seems that the library "libfreetype.6.dylib" cannot be found, but I must confess I have no idea what this @rpath is. Of course, I already tried to google this but couldn't find a proper solution. A "locate libfreetype.6.dylib" returns the following:

/Applications/TeX/TeXworks.app/Contents/Frameworks/libfreetype.6.dylib
/Applications/VLC.app/Contents/MacOS/lib/libfreetype.6.dylib
/Developer/SDKs/MacOSX10.5.sdk/usr/X11/lib/libfreetype.6.dylib

/Library/Frameworks/Python.framework/Versions/7.0/lib/libfreetype.6.dylib
/usr/X11/lib/libfreetype.6.dylib

Using the otool -L to see the different links of the last two files here's what I have:

>otool -L /Library/Frameworks/Python.framework/Versions/7.0/lib/libfreetype.6.dylib
/Library/Frameworks/Python.framework/Versions/7.0/lib/libfreetype.6.dylib:

  /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 550.34.0)

And then, I'm completely lost and I have no idea how to proceed. Anyone has an idea how to solve this ?
Thanks a lot,

Johan
