This is primarily a bug with the libgd installation, which can't
find the arial font.  However, I think there's a case for saying
there's a minor gnuplot bug here: given the terminal setting
quoted above, why is gnuplot giving the error message about arial?
Isn't "small" a directive to use the libgd internal font?

(Off topic here, but gretl -- a third party caller of gnuplot --
is getting confused by that error message; it doesn't expect it
because previous gnuplot versions didn't emit it.)
