Wat is your current status?
Did you allready install Mambo?
In which case mysqlsupport is avail. The rest you can check at the back end.
Toolbar help-> tag system info.
If not installed. You could make a very complex php script!

Create a file phpinfo.php and put this line in it
<?php phpinfo(); ?>
Save it in your web root.
Enter in your browser
www.yourdomain.com/phpinfo.php
or if applicable
localhost/phpinfo.php
A list of info will be shown of all that is available to php.
If mysql is not mentioned. The support is not there. Current versions it is mostly build in.
Zlib enabled, should be found in there as well. Can be set in the php.ini file.
For safety reasons remove that little script from your root, because it is great for hackers to examine your environment.
I hope this helps?
