I have a toolkit that uses aggdraw to generate graphic files. On various systems, it seems to work fine with Python 2.4 and 2.6, but with Python 2.5 I get this error:

IOError: Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/RDKit_Q32009_1/rdkit/Chem/Draw/__init__.py", line 104, in MolToImageFile

drawer.AddMol(mol,highlightAtoms=highlightAtoms)

font = Font(color,faceMap[font.face],size=font.size)
IOError: cannot load font (no text renderer)

I've googled and found mention of others having a similar problem, but I have yet to find a resolution apart from a different version of Python.

Any advice or insight is greatly appreciated.

There must be somthing broke in 2.5 version that was fixed in 2.6
