note 38942 added to ref.vpopmail

Im having trouble calling on these vpop functions I have the following setup: Apache2.0, PHP 4.3.4 i did, ./configure' '--with-apxs2=/usr/local/sbin/apxs' '--with-mysql' '--with-vpopmail=/usr/local/vpopmail' I have this very simple page and I get the following error: Fatal error: Call to undefined function: vpopmail_add_user() in /var/www/add.php on line 16 Did I not do the setup correctly? Do i need to add anything to http.conf or php.ini? What am I missing here?
