[horde] Horde: No such file or directory errors

[Per olof Ljungmark]

Sorry for the cross posting but I am really not sure where this belongs.
The performance of our H4 test install is not good at the moment and I
need to find out why.

In looking at the Apache process with truss there are lots of errors
like the below.

How can I make Horde look in /usr/local/share/pear/Horde/ instead of
first trying the webroot?

This is on FreeBSD 8-STABLE.

access("/usr/local/www/horde4/imp/lib/../../lib/Alarm/Handler.php",0)
ERR#2 'No such file or directory'
access("/usr/local/www/horde4/lib/Alarm/Handler.php",0) ERR#2 'No such
file or directory'
access("/usr/local/www/horde4/lib/Horde/Alarm/Handler.php",0) ERR#2 'No
such file or directory'
access("/usr/local/share/pear/Horde/Alarm/Handler.php",0) = 0 (0x0)

Thanks,
