[PHP-INSTALL] Mediawiki - error message "for mysql, compile PHP using -with-mysql

[Gregg b Sales]

I am trying to install MediaWiki 1.8.2.  I have istalled MySQL and PHP 
5.2.0.  The error I get from MediaWiki is:

PHP 5.2.0 installed Could not find a suitable database driver!
For MySQL, compile PHP using --with-mysql, or install the mysql.so module

I am running IIS on a Win2000 Server box.

Can anyone help?
