Why can't Horde cannot find files in php folder?

Question

I have Horde installed on a RHEL 6 machine running Apache. When I launch it, I get a

"PHP Fatal error: require_once(): Failed opening required 'Horde/Autoloader/Default.php'

My files are loaded at /var/www/horde/ My php files are loaded at '/usr/share/pear/'

The file that it's looking for is at '/usr/share/pear/Horde/Autoloader/Default.php'

My httpd.conf file points to /var/www/horde

When I put in localhost it finds my index.php in the horde folder.

How do I configure it so that the files in the php folder can be found?

Answer 1

Ok, so I added a line to my php.ini which set the include_path which seems to fix my problem.
