Hi William,
don't know if these note can help to know where is the problem :
The matplotlib freetype libs are build with both architecture :
GRASS 6.5.svn (spearfish60):~ > file /Library/Python/2.6/site-packages/matplotlib-1.0.svn_r7892-py2.6-macosx-10.6-universal.egg/matplotlib/ft2font.so

GRASS 6.5.svn (spearfish60):~ >
if i try to run matplotlib "import ft2font" from a grass shell, it fails if i use the standard python executable (python, python2.6, pythonw)
while it ("from matplotlib import ft2font") works if i run it from "grass->ipython"

thanks for any suggestions to debug thisproblem.
ciao,

But in the case of a statically linked library, maybe ft2font.so (matplotlib) is the right arch, but the linked freetype was not. Because of the way Python modules are linked, you don't get link errors so you don't know until you run it.
