import pdflib-lite-7.0.3
This is a newer version of what we have as pkgsrc/print/pdflib, but
it comes with much unfriendlier licensing conditions (non-commercial
use only).
I've tested it with gnuplot. There is just some "dash patterns" support
added over pdflib4 afaics. So making it the default choice isn't worth
the hassle, but if you want to try it, here is it.
