zope.interface and other newbie questions

[gary_p]

Apologies if this is the wrong place to ask:

1. What is codenode? Is it the notebook part of sage with the math
removed? (The reference to sage on the homepage confused my little
brain.)

2. I don't see instructions for starting codenode. After some
hunting I did
codenode-admin init codenode
cd codenode
codenode-admin run

Is that the way?

3. I'm on Kubuntu 9.10. I installed using virtualenv and pip, my
first experience with virtualenv and pip. After installing, and
trying to start as above I get an exception:

(codenode)gap@gap-laptop:~/Documents/python/virtualenv/codenode$
codenode-admin run
Traceback (most recent call

from zope.interface import
Interface
ImportError: No module named zope.interface

out of curiousity, I did
$ pip install zope.interface
Requirement already satisfied: zope.interface in /usr/lib/python2.6/
dist-packages
Requirement already satisfied: setuptools in /usr/lib/python2.6/dist-
packages (from zope.interface)
Installing collected packages: setuptools,
zope.interface
Successfully installed zope.interface

but codenode still can't find it.

any ideas?
