Running from the 1-Apr-2008 CVS snapshots, DIMP installed into an
operational Horde framework without IMP allows you to configure DIMP, but
when clicking Options for DIMP generates a PHP fatal error:
Fatal error: require_once() [function.require]: Failed opening required
'/home/bishop/www/staging/horde/config/../imp/lib/Notification/Listener/status.php'
(include_path='.:/usr/local/lib/php/') in

line 3

DIMP should gracefully degrade in this situation, perhaps by providing a
nice message stating that IMP is not installed.  Better, IMO, would be to
prevent DIMP configuration absent a configured IMP install.
