mod_rewrite Apache module for WordPress

[MzaNike]

Hello eveybody.

Wordpress expects:
PHP 5.2.4 or greater
MySQL 5.0 or greater
The mod_rewrite Apache module

I am currently installing PHP 5.4 based on this documentation (Hopefully it works)
My SQL is given by default in Plesk 9.5.4
But what do I do with the mod_rewrite Apache module?

I would appreciate any suggestion on how to enable this.

Thanks
Michae

PS: I haven´t updated to 10.x, because no hMailserver support :-(
