I'm running Apache 2 and PHP 5 on Ubuntu and trying to set up a punBB forum. Whatever I do, though, I get this message when I run install.php:

"This PHP environment does not have support for any of the databases that PunBB supports. PHP needs to have support for either MySQL, PostgreSQL or SQLite in order for PunBB to be installed."

I went so far as to uninstall and reinstall Apache and PHP, making sure that mysql.so was enabled in /etc/php5/apache2/php.ini. I know that my mySQL database is working OK-- I keep my music library in it.

Any ideas? Other Ubuntu/Debian/Linux users out there that can help me with any dumb configuration mistakes I might have made?

EDIT: Sorry, I forgot to post my phpinfo() page. It's http://www.cahsmic.com/testphp.php
