Comment (by jjstickel):

 I got `gvedit` to configure, but then nothing was built (nothing to do for
 `make all`).

 I also managed to build and install `graphviz-gui`, but it seems rather
 useless. I can edit an attribute once, and the graph in the viewer
 changes, but then any more attribute edits do not take effect.

 So, my question is this:  is it worth keeping the gvedit and graphviz-gui
 portfiles? They do not seem very useful, and keeping them around may
 hinder future updates to graphviz (as is happening now). Or at least
 remove gvedit. We can keep graphviz-gui for now since it at least builds
 and installs.
