OK, so it works fine in gnuplot.
That seems to indicate that both gnuplot and libgd are working fine.

Which suggests that gretl is running in a different environment
and therefore doesn't see your GDFONTPATH.

I don't think so.  Your first test demonstrates that libgd is able to
find the font correctly.  Does gretl maybe scrub its environment on entry?
