When I attempt to Install Mediawiki I get this after typing in all information:

Checking environment...

    * PHP 4.3.2: ok
    * PHP server API is apache2filter; using ugly URLs (index.php?title=Page_Title)
    * Have XML / Latin1-UTF-8 conversion support.
    * PHP's memory_limit is 32M. If this is too low, installation may fail!
    * Have zlib support; enabling output compression.
    * Neither Turck MMCache nor eAccelerator are installed, can't use object
caching functions
