Hi Tpc,

'rpy' has a few prerequisites.  You need to first install R, because 'rpy'
is a translator between R and Python.

    http://www.r-project.org/

It is Free Software, so you should be able to grab it from several
mirrors.

This may be an issue with not having R installed: it sounds like the
system is trying to do its best to find R, but without success.


If you're having more problems with 'rpy', it might be best to bring them
up on 'rpy-list':

Good luck!
