Need help with PDFlib under Linux

First some background. I have two "servers": 1) Windows XP with Apache 1.3.26 and PHP 4.2.2 2) GNU/Linux with Apache 1.3.26 and PHP 4.2.3 compiled in statically Both are working well, but I now want to add PDFlib support to both servers. On the win32 machine it was as easy as uncommenting out php_pdf.dll line in php.ini and it was working great. What is the best/easiest way to get PDFlib working on my Linux server? I don't have PDFlib itself installed on EITHER system (other than the precompiled DLL on Windows). Does the PHP source come with all the code necessary to compile php_pdf.so or do I need to install PDFlib, libtiff, libjpeg, libpng, libz....all from their respective sources in order to do this? Thanks. -- Cameron
