[resolved] rcube_mysql.inc missing

[jmkaza]

During the install /installer/test.php is calling /include/rcube_mysql.inc, which doesn't exist.
The error is as follows...

Warning: main(include/rcube_mysql.inc) [function.main]: failed to open stream: No such file or directory in /home/socals4/public_html/rcmail/installer/test.php on line 48

Fatal error: main() [function.require]: Failed opening required 'include/rcube_mysql.inc' (include_path='/home/socals4/public_html/rcmail/program/lib:/home/socals4/public_html/rcmail/program:.:/usr/lib/php:/usr/local/lib/php') in /home/socals4/public_html/rcmail/installer/test.php on line 48

line 48 is ($DB->db_connect('w');
I'm sure where 'w' is declared yet.

Am I missing a file or is the call supposed to be using a default file instead of rcube_mysql.inc?
Any help would be greatly appreciated.
Thanks,
J.

There is no rcube_mysql in RoundCube. You configured the wrong "backend lib" to use. Use either "db" or "mdb2".

(mdb2 is recommended!)
