#13 setup.py should also install Peapod.download module

Setup.py is only installing modules peapod, tagging, OPML, btclient and feedparser.

This results in the following message when running /usr/bin/peapod.py:

Traceback (most recent call last):
File "/usr/bin/peapod.py", line 7, in <module>
from Peapod.peapod import getConfig, newTracks, feedLog
File "/usr/lib/python2.5/site-packages/Peapod/peapod.py", line 35, in <module>
from Peapod.download import downloadURL
ImportError: No module named download
