----------------------+----------------------
 It is impossible to install the +rsvg variant of graphviz, as there is the
 following dependency cycle:

 "graphviz +rsvg" depends on "librsvg" which depends on "vala" which
 depends on "graphviz".

 Terminal output:

 {{{
 % sudo port install graphviz -x11 +rsvg
 --->  Computing dependencies for graphviz
 The following dependencies will be installed:
  graphviz
  librsvg
  vala
 Continue? [Y/n]: y
 Error: The following dependencies were not installed because all of them
 have unmet dependencies (likely due to a dependency cycle): librsvg vala
 graphviz
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there is a bug.
 Error: Processing of port graphviz failed
