I thought Mailman was supposed to be platform independent... I didn't have 
this particular problem with v2.0.13 but I guess this must be some thing 
new related to mailmanctl.

As far as rewriting this code goes, I'm a bit stuck because, a) I don't 
know Python, b) I don't know what the purpose of the code is. Maybe I can 
just comment it out...
