PDF Library Not Working (Call to undefined function)

I RTFM but did not find a solution. My head hurts from banging it against = the wall. :-P Apache, OpenSSL, MySQL and PHP work fine... but the PDF libraries will not = work. I used the following configure commands: PHP: './configure' '--with-mysql=3D/usr/local/mysql/' '--with-xml' = '--with-apache=3D../apache_1.3.22/' '--with-curl=3D/usr/local/curl' = '--enable-shared-pdflib' '--enable-track-vars' PDFLib: Almost defaults... just turned off Python and C/C++. I can provide a complete list of configure options and the order they were = executed if you need them... The error message when attempting to use the PDFLib functions is: Fatal error: Call to undefined function: pdf_new() in /usr/local/apache/htd= ocs/program/dmipps/pdfdemo.php on line 2 Thanks for any help, it's really appreciated.
