[dev] Trean upgrade script fails to run

[Joe Jenkins]

When attempting to run

./2004-12-03_use_datatree_attributes.php

I get the following error:

PHP Fatal error:  Cannot instantiate non-existent class: 
datatreeobject_bookmarks in 
/horde/trean/scripts/upgrades/2004-12-03_use_datatree_attributes.php
on line 37

My horde install is up to date and is working fine everywhere else but 
Trean.

Thanks and Happy Holidays!
