It would be nice if we could move all of these Python deps into
buildout. Indeed, I think that's the plan.

However, for a personal project, I noticed that, despite ample love,
promises of wealth, incredulity, anger and threatening behaviour,
psycopg2 would not install using buildout alone. I had to set up a
virtualenv, run buildout within it, and use a pip recipe:

[psycopg2]
recipe = gp.recipe.pip
virtualenv = .
install =
    psycopg2

(I think I could also have used easy_install within the virtualenv, but
I still wanted buildout to wrap the installation process as much as
possible.)
