Move a Pinax project - pinax

Question

(Cross post from Pinax Users Google group -- I figured it would be useful to have this question on here as well.)
I'm a bit stuck. My projects work fine when I run them on the original machine I create them on, but I get an error when I move them to another machine. I'm trying to use hosted version control to manage a project between two computers, but it only works on the machine I create it on. I'm just trying to get the project base "zero" to run on both machines. Here's the console output I'm getting when I run manage.py runserver:
Traceback (most recent call last):

I expect that this has something to do with my pythonpath, but I'm just too new to this to know where to look. I dug up this thread, but I couldn't find a solution in it:
Django failing to find apps
Help would be great!
