Which version of graphviz? How did you install it?

Which version of R? How was R installed? How did you install
Rgraphviz and which version?
I'm guessing that you installed the OS X binary version of Rgraphviz.
That is compatible with the graphviz binary downloadable from here:

Yes, it is an old version. If you want to use a more recent graphviz,
you will need to be able to install Rgraphviz from source.
