Problem with MySQL Extension

Setup Linux RHEL 3, PHP 4.3.2, MySQL 4.1.12 I am trying to use phpMyAdmin to connect and I am running into trouble. I get the message that PHP can not load mysql extension. A check of /usr/lib/php4 shows mysql.so is where is should be and under /etc/php.d there is the correct mysql.ini, along with imap, odbd and ldap which all show up with a call to phpinfo(), but mysql does not. I upgrade the php-mysql extension from 4.3.2-8 to 4.3.2-23, which is the most current rpm and still no luck. I now get the message that it can't find mysqli extension. Any ideas?
