Hmm, I suspect your are getting caught by having more than one version
of graphviz installed on your system.  Here are a few things to try...

In R, do:

rglibs <- system.file("libs/Rgraphviz.so", package="Rgraphviz")
system(paste("otool -L", rglibs))

This will only work, I suspect, if you have the Xcode tools installed
already, but it should tell you which version of graphviz, your
Rgraphviz is linked against.

+ seth
