Returns:

<module 'twisted' 
from '/var/lib/python-support/python2.5/twisted/__init__.pyc'>
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute '__version__'

Tried that. Didn't make huge difference, so I tried 'apt-get purge' instead, 
followed by 'apt-get install'.
Running bin/tahoe --version now reports:

Traceback (most recent call last):
