There are actually 2 virtualenvs for mailman. One is the default one
that you are working in, another one(venv-3.4) is probably automatically
created by mailman-bundler as you can see in the logs above.
This should fix your problem.

  $ source /usr/local/src/mailman-bundler/venv-3.4/bin/activate
  $ pip install psycopg2
  $ (reactivate your original venv)
