[sork] Horde 3.0-RC2 and Sork

[Chris]

Hi List,

Sorry if this has been convered before but i've had no luck finding the 
solution so far.  I have a test environment with:

Horde 3.0-RC2
Imp 4.0-RC2

which works perfectly.  I wanted to install the sork modules to provide 
some extra functionality.

I initiall installed Account, Vacation and Forwards all versin 2.2.1 
however when i try to access the module i recieve and error message like 
this:

Warning: main(/var/www/horde/vacation/lib/Test.php): failed to open 
stream: No such file or directory in /var/www/horde/vacation/index.php 
on line 21

Fatal error: main(): Failed opening required 
'/var/www/horde/vacation/lib/Test.php' 
(include_path='.:/usr/share/php:/usr/share/php/PEAR') in 
/var/www/horde/vacation/index.php on line 21

i'm really not sure where i should be looking to fix this problem so any 
  advice is greatly appreciated.
