| Ok, I couldn't check the png terminal on my rough gnuplot 4.2.2
| installation. I suppose that in fact the best way to deal with this is to
| have a fontname "default" and don't try to set the fontname at all if the
| fontname is "default". However this might cause issues with the TeX
| \fontname option, but I think we can live with that

I'm not sure I see the need to fix this problem.  Isn't the message
from gnuplot just a warning?
