[kronolith] Fatal error when adding events within Kronolith

[Jon-Michael DeShazer]

I keep getting this error every time I attempt to add new events to a 
calendar using kronolith:


  A fatal error has occurred


      DB Error: extension not found

|[line 542 of /var/www/localhost/htdocs/horde/kronolith/lib/Driver/sql.php]
|

|I have no idea why.  Here are my specs
|

|Gentoo Linux 2005.1
horde 3.0.7
kronolith 2.0.5
PHP 5.0.15
MySQL 4.1.15
Apache 2.0.55
|

I have the MySQL 4.1+ authentication method enabled and the correct user 
name and password for the database.  Any ideas?
