Unable to load DBIx::SearchBuilder database handle for 'Oracle'

I am new to RT and am trying to get it running with oracle and FastCGI.
Everything seems to have installed and initialized correctly but I am
having problems with the web server. I’ve been searching the list
archives with no luck. Any help with this would be much appreciated.

I am using RT 3.6.1, Oracle 9i, Redhat EL4 and httpd-2.0.

Here is the error message I am getting in /var/log/httpd/error_log:

[Wed Sep 27 11:32:08 2006] [warn] FastCGI: server

Perhaps you’ve picked an invalid database type or spelled it
incorrectly.
