ITYM s/maintains/is in Uploaders of/. It makes a big difference here...

Note that python-imaging is only a compatibility package. It would be 
better to port biopython to the new PIL API.

I came to the same conclusion. I've attached what seems to be a minimal 
test-case:

$ python test.py
Warn: Can't find .pfb for face 'Times-Roman'
Traceback (most recent call last):
 File "test.py", line 6, in <module>

If I understand correctly, reportlab is trying to use non-free Adobe 
PostScript fonts, which (unsurprisingly) doesn't work on Debian systems. 
It should use the substitutes from the gsfonts package instead.
