Comment (by rjvbertin@…):

 Here's what Ryan wrote about the issue - but for port:kgraphviewer :

 >libgraph was the old graphviz library, retired quite awhile ago now in
 favor of the libcgraph library. libgraph was deprecated in graphviz 2.30.0
 in January 2013 and removed in graphviz 2.36.0 in January 2014.
 kgraphviewer will have to be rewritten to use libcgraph instead. Did you
 already check if a newer version of kgraphviewer exists with this change
 already made?

 I just tried again: the port builds for me ...
