[turba] Fatal-Error non-existent class

[SAJChurchey]

I'm trying to install H3 with a lot of modules. All of the others are coming
up fine, but when I try to look at the Address Book, I get the following:


Notice: Undefined index: imsp in /usr/share/horde3/turba/config/sources.php
on line 490

Notice: Undefined variable: GLOBASL in
/usr/share/horde3/turba/config/sources.php on line 491

Notice: Undefined index: imsp in /usr/share/horde3/turba/config/sources.php
on line 492

Fatal error: Cannot instantiate non-existent class: imsp_auth in
/usr/share/horde3/lib/Net/IMSP/Auth.php on line 107

I'm pretty sure I installed all of the files. I'm using Debian 3.1 with
Apache 2 and PHP 4 and a MySQL 4 as the db. Any ideas on what I should be
looking for or where to look?

Not necessarily a related problem: I'm also having troubles with posts,
events, notes, etc. not showing up on the interface. Looking in the db all
of my additions are show; they're just not displayed in horde. This is
pretty much for any module atm. I'm using Turba, Mnemo, IMP, Kronolith and
nag. *
