Yes, we really have a duplication
https://github.com/stackforge/fuel-web/blob/master/nailgun/requirements.txt#L8

We need to try to remove it from test-requirements
https://github.com/stackforge/fuel-web/blob/master/nailgun/test-requirements.txt#L6

It's sad, that pip couldn't handle such simple cases :(

postgresql-dev package should be installed, I guess

[Aleksey Kasatkin (alekseyk-ru)]

You are right. It goes well with postgresql.

The last thing is for 12.04 only. It's all OK with 13.04.
