Missing /opt/local/etc/ansible directory after install

[macports@…]

I installed sysutils/ansible (​http://www.ansibleworks.com/) but there was no /opt/local/etc/ansible directory created.

If one clones their git repo and does the port install using their Portfile, one gets:

/opt/local/etc/ansible/ansible.cfg /opt/local/etc/ansible/hosts

Arguably the hosts file isn't required, because it's just examples. But it seems to me that the cfg file should be installed.
