Has anyone here used these programs?

Zope is an open-source, object-oriented web application server written in the Python programming language....
Plone is an open-source content management system built on top of the Zope application server.  
Plumi is a Free Software video sharing Content Management System based on Plone

I have installed Zope and Plone, and they seem to be working fine....but I cant figure out how to install Plumi...being the feature I really want...

I have read the installation instructions, but it seems beyond me....can anybody offer me any help on this?
