I've installed Red Hat and XAMPP, now I'm trying to install phpBB2. I'm able to see all of the XAMPP info and phpinfo() but when I try to open install.php I receive the following errors: Warning: include(./../extension.inc) [function.include]: failed to open stream: No such file or directory in /opt/lampp/htdocs/phpbb2/install/install.php on line 314 Warning: include() [function.include]: Failed opening './../extension.inc' for inclusion (include_path='.:/opt/lampp/lib/php') in /opt/lampp/htdocs/phpbb2/install/install.php on line 314 Warning: include(./../includes/constants.)

I'm sure that it's looking for includes, but I'm not sure where they are or what I can do to fix it.
