There is a README for the Rgraphviz package, available here:

http://bioconductor.org/packages/release/bioc/readmes/Rgraphviz/README

It says that you need to install graphviz first, preferably version
2.26.3, from here if you are running Snow Leopard or newer:

http://www.graphviz.org/pub/graphviz/stable/macos/snowleopard/graphviz-2.26.3.pkg

And from here if you are running Leopard:

http://www.graphviz.org/pub/graphviz/stable/macos/leopard/graphviz-2.26.3.pkg
