complie FDF with PHP on FreeBSD

Has anyone successfully compiled Forms Data Format function for PHP on FreeBSD? I know at the php site http://us4.php.net/manual/en/ref.fdf.php, they said that the platforms supported by Adobe are only Win32, Linux, Solaris and AIX. The tool kit you download at the adobe web site only contain “.so” files for those systems. BTW, you can download the fdf SDK tookit at http://partners.adobe.com/asn/acrobat/sdk/regeula/fdftkv5.tar.gz However, I know that FreeBSD supports Linux binary. Has anyone find anywork around to get php FDF function to compile under FreeBSD. Can’t FreeBSD somehow use the Linux “.so” file? I really would like to use FreeBSD, but I also need to use FDF. Anyone? Any inputs? Thanks. Tree
