I have just downloaded and installed it on my server as well - but the main page looks completely different.
There seems to be formatting issues with your installation.

Line 53 of Setup.php is require_once( 'OutputPage.php' );
OutputPage.php houses the class not being found on your server.  Check to see that the file exists mediawiki/config/OutputPage.php

If the file mediawiki/config/OutputPage.php did not exist, then the script would have failed at Line 53 of Setup.php.
require_once( 'OutputPage.php' );

What's on line 291 of Setup.php?
Line 291 of Setup.php:
$wgOut = new OutputPage();

Which is where it dies.  I've done a search through the file and the class is only declared there.
I don't understand it either.  WilliamFrantz is right - if my Setup.php is the same as rhinez0rz, then the script should generate the error on line 53.  

What happens to require_once() calls under different errorchecking settings?  Would it ever be ignored if the file does not exist if error reporting is set to NONE?

output.php doesn't exist on my server and it doesn't exist in the package I downloaded and uploaded to the server.
The file is called 'OutputPage.php' not 'output.php'.  I'm pretty sure you have it or the script would have died on line 53.  Although, this entire topic is making me question what require_once() actually does.

What version did you download? I'm using 1.6.3... maybe thats the problem?
rhinez0rzAuthor Commented:
I think it has something to do with my php version. It's below the reccomended versions mentioned in the install.
I downloaded MediaWiki 1.6.3
I am running PHP Version 5.0.5 and MySQL 5.0.15-nt.
Perhaps it is because your PHP is below specs.
