[horde] Warning: main(PEAR.php): failed to open stream

[RYAN vAN GINNEKEN]

Trying to set up horde on freebsd 5.3 stable but am getting the below 
errors on the virtual host i set up.  I tried to login originally using 
http://localhost/horde/ but kept getting page not found error so i 
pointed a virtual server at /usr/local/www/horde which contains the 
index.php file
