[SciPy-user] Trouble installing on OSX 10.4 Intel

[David Andrews]

Hi Gaël,

Doing as you suggested produces errors with regards to libfreetype as follows:

>>> from pylab import *
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/pylab.py",

    from matplotlib import ft2font
ImportError: Failure linking new module:
/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/matplotlib/ft2font.so:

  Referenced from:

  Reason: image not found

I think that simply copying the __init__.py from a 'working' release
of matplotlib isn't enough.  As I understand it freetype is only a
requirement in the compilation of matplotlib.
