Mediawiki install problems

I have installed mediawiki with the one click and followed the instructions as outline in the email sent from the folks at dreamhost. I enter in all the config stuff and then it says that the install is good to go.

I moved the .php file that they said to move to the base directory and then click the link that is supposed to take me to my wiki.

Here is what I get:

Error, Setup.php must be included from the file scope, after DefaultSettings.php
