[Jonathan Bell]

I followed install instructions to the letter. But when i get to:

To finish installation, run the installation script on the command line 
and answer all questions:

webmail-install


I get this.....


Warning: require_once(/lib/Application.php): failed to open stream: No 
such file or directory in /usr/local/bin/webmail-install on line 17

Fatal error: require_once(): Failed opening required 
'/lib/Application.php' 
(include_path='.:/usr/lib/php:/usr/local/lib/php') in 
/usr/local/bin/webmail-install on line 17


I can see Application.php in the /lib directory.
