easy_install ReviewBoard [Errno 104] Connection reset by peer

I have a Kubuntu 10.04 VM image and am trying to install ReviewBoard by following The Linux Installation Wiki. When I get to the step to easy_install ReviewBoard, I encounter a problem I cannot find a solution to. Below is the console output:

I am new to python, but it seems like easy_install cannot decide on a version of pytz. I have read

• 104, 'Connection reset by peer' socket error, or When does closing a socket result in a RST rather than FIN?
• http://homepage.mac.com/s_lott/iblog/architecture/C551260341/E20081031204203/index.html

and it seems like the problem described in those articles has more to do with development than my problem, but I could be wrong.

Has anyone encountered a problem like this? If there is any missing information that would help troubleshoot this, please let me know.

EDIT: I'm not sure if this will be more useful information, but I tried installing the gitplugin for Trac and I received the same issue. So, it's looking like it may be a problem with easy_install.

>> sudo easy_install http://trac-hacks.org/svn/gitplugin/0.11

error: Download error for http://trac-hacks.org/svn/gitplugin/0.11: [Errno 104] Connection reset by peer

This is possibly a temporary problem with PyPI host, try again: easy_install pytz
