UserWarning: Module ansible was already imported

I just cloned the ansible repo, tried sourcing hacking/env-setup and this is the warning I get when I run ansible --version:

`
$ source hacking/env-setup

Setting up Ansible to run out of checkout…

PATH=/home/vagrant/tmp/ansible/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/home/vagrant/bin
PYTHONPATH=/home/vagrant/tmp/ansible/lib:
MANPATH=/home/vagrant/tmp/ansible/docs/man:

Remember, you may wish to specify your host file with -i

Done!

I don’t remember seeing this before the modules were moved to separate repositories. Does the env-setup script need updating?
