version 3 of pdflib has odd restrictions for usage (and you may need to
purchase a license depending on what you do with it). It is however needed
for php4's pdf functions and is of use to many, so we'll keep a seperate
restricted port available for those of us who need it.
Support for languages other then C/C++ are turned off for now, but I may change
that (turning on perl/tcl/python support involves turning _off_ C/C++ support,
so I'll add a WITH_FOO knob later)
