Comment (by mascguy):

 As part of the effort toward updating graphviz via Jonathan's PR, the
 Devel port (graphviz-devel) has now been updated to 2.48.0. And all three
 components - the based port, as well as both GUI subports - appear good as
 well.

 Can you folks uninstall your non-Devel graphviz ports, and install the
 Devel versions? (graphviz-devel, graphviz-gui-devel, gvedit-devel) Thus
 far, everything looks good based on my local testing. The only caveat: The
 numerous graphviz variants have not been fully validated, so there may be
 some minor issues.

 In any case, the more we can validate these ahead of time, the better.
 Please give them a try, and provide feedback.
