I remeber having this problem, but cannot remember how I resolved it!
First, check that your php and Apache are talking to each other by creating a php file with the line
phpinfo(); ?>
and save it as index.php then call it from your browser with
http://domain/index.php. If you get a screen about your php config, then you know that has worked OK.
If it doesn't do that, then go back and check your Apache\php config. I use IIS though, so cannot really help you much more than that. For any other XOOPS user to help, can you let them know whether you are on a network or doing it standalone?
Also, try downloading and installing 'xsas'. Do a search for it on this site and you will find the link. That configures loads of php, MySQL and Apache stuff for you. Oh yeah, you do have MySQL installed I take it?
