[horde] Problem with Layout

[David Bates]

Not sure if this is a Horde or a Kronolith Question.. 

But I had a setup for my layout and at this time I can't remember what they 
were, but now after updating the Framework and such I'm getting this error.. 

Warning: main(Horde/History.php): failed to open stream: No such file or 
directory in /var/www/html/horde/kronolith/lib/Driver.php on line 3

Fatal error: main(): Failed opening required 'Horde/History.php' 
(include_path='.:/usr/share/pear') in /var/www/html/horde/kronolith/lib/Driver.
php on line 3

Any ideas guys?

Like I said, I'm posting here cause I was unsure if it was a Framework  (horde 
core) or a Kronolith problem..
