I am trying to install MediaWiki 1.4.0 on 5.3-STABLE FreeBSD 5.3-STABLE following the instructions at

http://meta.wikimedia.org/wiki/Running_MediaWiki_on_FreeBSD

I have installed all the ports

But when I load index.php, I get the following message

MediaWiki 1.4.0 installation

Please include all of the lines below when reporting installation problems.

Checking environment... • PHP 4.3.10: ok • PHP server API is apache2handler; ok, using pretty URLs (index.php/Page_Title) PHP's XML module is missing; the wiki requires functions in this module and won't work in this configuration. If you're running Mandrake, install the php-xml package.
