ruby-dbi is not shipped anymore in Debian (→ jessie).

As a result, OAR was removed from Debian testing.

TODO for 2.5.4

• remove drawgantt v1 from the packaging
• remove oaradmin from the packaging
• write a new script to handle admission rules, in Perl.

A new script to handle the resources like oaradmin does could be rewritten later (not for 2.5.4).
