[BioC] topGO dependency: Rgrapphviz

[Thompson, Kevin]

Hi,

   FYI, I have recently updated the topGO package and it now appears the Rgraphviz is a dependency, although not listed as so.    I do have graphviz installed (2.28) installed on OS X am working on the configuration issue.  If anyone has any suggestions I would greatly appreciate them.

  Check that (1) graphviz is installed on your system; (2) the
  installed version of graphviz matches '2.26.3'; this is the version
  used to build this Rgraphviz package; (3) graphviz is accessible to
  R, e.g., the path to the graphviz 'bin' directory is in the system
  'PATH' variable.  See additional instructions in the 'README' file of
  the Rgraphviz 'source' distribution, available at
