 keep it, and gvedit as well, unless upstream has discontinued these
 products.

 Perhaps the version I built is not fully functional---I don't know because
 I haven't used it before. In any case, as a volunteer with a day job (as
 most Macports contributors and devs are, I know), I am willing and able to
 help with graphviz (the command-line tool), but not as much the GUIs.
 Someone more interested in those will need to contribute to keep them
 going.
