Setting up media wiki is driving me crazy!

I have tried it a couple different ways, once in my base dir and another in the wiki sub dir. Either way it keeps going back to the config/index.php page without any errors or anything and it doesn't create my LocalSettings.php file.

My permissions for the entire dir are set to user.user 777 on all files!

The setup says it is ok to run:

Checking environment...

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

* PHP 5.1.6 installed * Found database drivers for: MySQL * PHP server API is apache; ok, using pretty URLs (index.php/Page_Title) * Have XML / Latin1-UTF-8 conversion support. * PHP is configured with no memory_limit. * Have zlib support; enabling output compression. * Neither Turck MMCache nor eAccelerator nor APC are installed, can't use object caching functions * Found GNU diff3: /usr/bin/diff3. * Found GD graphics library built-in, image thumbnailing will be enabled if you enable uploads. * Installation directory: /home/httpd/html/wiki/wiki * Script URI path: /wiki * Environment checked. You can install MediaWiki.

Any ideas would be greatly appreciated!
