Resources/best practices for making a .deb out of a virtualenv

[Tim Chase <debian@tim.thechases.com>]

I've got a Python project where the dependencies are
isolated in a virtualenv and would like to package it up as a .deb
the purposes of sharing.  Normally I'd include the additional
libraries as straight-forward dependencies of the Debian package
itself, but some of the required package-versions conflict with the
stock Stable or Installation packages (e.g. Django 1.4 in Stable vs.
1.6 or 1.7 which are more current versions).

Are there any good resources on how to package up a virtualenv for
distribution so that it can use more recent libraries?

(I'm not currently subscribed to the mailing list, but will if that's
easer than just CC'ing me or Reply-All'ing me).

Thanks,
