It's already interesting to know that it's not "pdf" but
which matters. And enabling this is of course great news!
The trouble is that the alternative PDF driver (using pdflib) does
not handle fonts via fontconfig, so a font specification that
works fine for generating a PNG may fail if it's fed to pdflib.
E.g. I could say to pngcairo or pdfcairo
... font "Bodoni MT, 11" ...
but pdflib would make nothing of this.

sorry what I meant wasn't "not available" but "not easily
understandable", "confusing". I think you even agreed on that a
OK, got you. Yes, I'd have to agree. It may be worth preparing
some notes for the gretl manual on the (quite small) subset of
gnuplot commands that a user might want to use when tweaking a
graph for printing/publication.
