so I think the issue is almost clear: the order of include paths.

when

PHP Code:

include "RVSeagullMod/lib/SGL/FrontController.php" 


it searches FrontController.php in order of include_path

you wish it get
/usr/local/lib/php/RVSeagullMod/lib/SGL/FrontController.php
instead of
/usr/local/lsws/lsphp5/lib/php/RVSeagullMod/lib/SGL/FrontController.php

then try to change include_path in php.ini to
.:/usr/local/lib/php:/usr/local/lsws/lsphp5/lib/php
etc
