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

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"
