Currently graphics/leptonica builds math/gnuplot without an option to turn it off even though it isn't listed as a dependency.
math/gnuplot has switched to being a full X11 graphical application and made math/gnuplot-lite if only the cmd utility is needed.
This makes graphics/leptonica build lots of X11 and GTK+2 dependencies that shouldn't be needed.
