PHP can not find core function

[doug at safeport.com]

I am trying to evaluate two php billing programs, One gives no errors, syntax 
or otherwise, the other fails to find the mysql_real_escape_string function.

I the later case I assume I have a path problem. It seems that something in the 
code of the first program is turning off errors. Both programs work on FreeBSD 
4.11 and php4. The failing system is FreeBSD 6.2 and php5.

My setup:

php.conf
   PHP_VER=5
   PHP_VERSION=5.2.4
   PHP_SAPI=cli cgi mod

php.ini is php.ini-recommended with the following changes:

   display_errors = On
   display_startup_errors = On
   ignore_repeated_source = On
   track_errors = On
   include_path = ".:/php/includes"

The following ports are installed:

   php5-5.2.4_1        PHP Scripting Language
   php5-session-5.2.4_1 The session shared extension for php
   php5-xml-5.2.4_1    The xml shared extension for php

phpinfo() shows the configure command as:

'./configure' '--with-layout=GNU' 
'--with-config-file-scan-dir=/usr/local/etc/php' '--disable-all' 
'--enable-libxml' '--with-libxml-dir=/usr/local' '--enable-reflection' 
'--program-prefix=' '--with-apxs=/usr/local/sbin/apxs' '--with-regex=php' 
'--with-zend-vm=CALL' '--disable-ipv6' '--prefix=/usr/local' 
'--mandir=/usr/local/man' '--infodir=/usr/local/info/'

I am not sure what else is relevant. I am quite lost, any help is greatly 
appreciated.
