I do well know these licensing issues (the other being the Linux code in 
Terminal).
xpdf made a leap forward and was relicensed in its latest release and 
now contains the "or later clause". The stupid part is however that I 
can't get PDFKit to work with the newer version, they removed one of the 
options needed to work as a library.
I made several attempts but failed failed and lost time. It would be 
nice to collaborate with the guy.
