I have recreated the virtualenv with --system-site-packages as you have
suggested and, when I launch python from the activated virtualenv, psycopg2
is successfully imported. However, I'm getting the following error when I
enter "sudo paster serve --reload development.ini", which appears to
indicate that the site packages clash with the virtualenv framework. Any
idea which package is causing the problem?
(testenv)[mpe25@au04uap210qanr2 testproj]$ sudo paster serve --reload
development.ini
