Configuring MySQL support for PHP

[sagar]

I migrated from Apache to Litespeed and all static content working fine. For PHP, I compiled 5.x version using litespeed webconsole. Now when I try to connect to mysql, I get following error:

This PHP environment doesn't have MySQL support built in. MySQL support is required if you want to use a MySQL database to run this forum. Consult the PHP documentation for further assistance.

I checked wiki/installation and did some search on google but could not figure it out.

I am a complete novice in all this, so would appreciate if some one could give me step by step instruction on how to setup mysql environment.
