[tahoe-dev] No module named python....

[Zooko Wilcox-O'Hearn]

Oh, I have an idea.  Let's factor out Tahoe-LAFS and just figure out  
if Twisted and/or Nevow are installed correctly on your system, quite  
apart from Tahoe-LAFS.  Just run the following test when you are in  
the "reinstalled Twisted" state, as described below:

Okay, now try again the two commands that you tried just before you  
did sudo apt-get install python-nevow:

python -c 'import twisted;print twisted;print twisted.__version__'
python -c 'import twisted.python;print twisted.python'

Please send me the output of that as well as the full output from  
"bin/tahoe --version".

Thanks!
