Your web server does not appear to support any common database types
I'm hosting my site on a local server, NATing port 80 traffic on my firewall to a private IP (and of course I can hit the installation script as well as index.html from a browser on another local machine.)
What am I missing?
Make a file called phpinfo.php in your docroot and put in it 2 lines:
<?php phpinfo()
Then bring that up in your browser (probably localhost/phpinfo.php) and look for a MySQL section. Check if it looks good. Let us know what it says there.
