The CCN project page is at https://launchpad.net/ccn (browse the code).
Here are quick installation instructions:
You'll need python (of course), CherryPy, and later on - we'll try to sort out what else :)
install bazaar
create an empty folder and cd there
bzr init (only once per folder)
bzr pull --remember lp:ccn
(if there's an upgrage later on, just cd to the folder and do: bzr pull)
Copy (app.conf.development to app.conf (use app.conf.production if it's the actual server), and edit it wisely
Do python app.py and point your browser to http://localhost:8080 (or whatever you wrote as server.socket_port in app.conf)
Note: There's no setup utility [yet], so easy_install (or apt-get etc.) whatever's missing
