Problem with PHP and MySQl after install

1) Installed MySQL 4.0.12 2) Installed PHP 4.3.1 One of my config options was --with-mysql=shared,/usr 3) added the following to /etc/ld.so.conf and ran ldconfig: /usr/lib/libmysqlclient.so /usr/lib/mysql 4) When I try to run phpmyadmin, I get the following error: cannot load MySQL extension, please check PHP Configuration. 5) Looking at the explanation of the errro still leaves me baffled on how to proceed: [1.20] I receive the error "cannot load MySQL extension, please check PHP Configuration". To connect to a MySQL server, PHP needs a set of MySQL functions called "MySQL extension". This extension may be part of the PHP server (compiled-in), otherwise it needs to be loaded dynamically. Its name is probably mysql.so or mysql.dll. phpMyAdmin tried to load the extension but failed. What was I missing fom my install that is causing my problem?
