compile fdf for php on freebsd 5.0

[treeml at itree.org]

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.
