[sork] problem installing sock vacation module

[gui]

Hi everybody

I'm trying to install the vacation module (vacation-2.2.2) of sock onto 
my system (horde-3.0.5 on Freebsd 5.4).   

I followed in the instructions in the INSTALL document.   Copied 
conf.php.dist to conf.php.
And modified horde/config/registry.php and horde/imp/config/conf.php 
according to the instructions in INSTALL.

The vacation icon appeared under Mail.   When I clicked on it, I got 
this error message:
"Warning: 
main(/usr/local/www/horde/vacation/lib/../../lib/Registry.php): failed 
to open stream: No such file or directory in 
/usr/local/www/horde/vacation/lib/base.php on line 23
Fatal error: main(): Failed opening required 
'/usr/local/www/horde/vacation/lib/../../lib/Registry.php' 
(include_path='.:/php/includes:/usr/local/lib/php/pear:/usr/local/share/pear') 
in /usr/local/www/horde/vacation/lib/base.php on line 23"

I then modified line 23 in base.php from "require_once HORDE_BASE . 
'/lib/Registry.php';"
to "require_once HORDE_BASE . '/lib/Horde/Registry.php';" .

After that, the first error disappeared but I got this error instead:
*Fatal error*: Undefined class name 'horde' in 
*/usr/local/www/horde/config/conf.php* on line *46
*
Then I made these three changes to vacation/config/conf.php
$conf['vacation']['path'] = '/usr/bin/vacation';
$conf['server']['driver'] = 'forwards';
$conf['server']['params']['default'] = array(
    'host' => '192.168.6.2',
    'port' => 21,

But the error still didn't go away.

Can anybody here help?

Thank you very much in anticipation.
