No mysql info through phpinfo();

Hi,

I am trying to install mantis, and I get errors when I try to run the install script saying that mysql is not configured to run on php.

I call the phpinfo() function and I see nothing relating to mysql.

I open the php.ini file, and, to be honest, it looks alright.

the extension_dir points to /usr/lib/php4 which includes the mysql.so extension.

Furthermore, I located the mysql.sock file and pointed the default socket to it, but nothing. what exactly am I missing?

if you wish to take a look at my phpinfo(), go here:

Thanks.

PS, This server runs several apps that use the mysql db program - most running on java, I feel as though I cannot totally reconfigure.

also, I do have the extension=mysql.so line in the ini file.
