This problem has been the subject of several posts to this list.

Its looks as if in a number of places code has been added that requires 
Python 2.0 or later, where many of the functions in the string module 
became available as methods on string objects.

That said, the 2.0.12 README only appears to say that later Python versions 
are preferred over Python 1.5.2 rather than saying they are required.

You probably need/want to upgrade to either Python 2.1.3 or 2.2.1 to fix 
your problem.

If you cannot upgrade to a higher version of Python than 1.5.2 then you 
will have to hack the source code so that where functions like lower have 
been used directly on string objects you instead call the lower function 
from the string module with the string objectect as the parameter to the 
call. For instance in case you have encountered, change:

         ack = msg.get('x-ack', '').lower()

to read:

         ack = string.lower(msg.get('x-ack', ''))

You may need to import the string module into the file concerened if that 
isn't already being done i.e. add this to the other imports at the top of 
the file concerned:

         import string
