I presume I was cc'd on this because I maintain qalculate-gtk that has a 
variant dependence on gnuplot. I personally do not use this variant, nor 
do I use gnuplot in any other way, and hence I do not much care about 
gnuplot. I can't speak for other users of qalculate-gtk, but I suspect 
they are few and will not notice a change. Nonetheless, making gnuplot4 
and gnuplot5 ports would be the Macports way, so that is what I recommend.
