Installing fdf support in php

I am working in a virtual server environment on FreeBSD with PHP4/apache (I don't have root access to the server). I would like to install fdf support. The install instructions that came with the package from Adobe are minimal. From reading the docs on php.net I understood that I could modify my apache httpd.conf with something like this: php_value extension_dir /usr/home/serverone/usr/local/lib/mylib php_value extension libFdfTk.so So far that isn't working. It looks like the two relevant files I need are: FdfTk.h libFdfTk.so I put both of these files in the directory I referenced above: /usr/home/serverone/usr/local/lib/mylib I am not clear if I need to put the FdfTk.h in a specific location and how I need to reference that. Any suggestions for how to proceed would be appreciated! Regards, Michael
