I have also installed numerous different versions of Rgraphviz/graphviz in an attempt to get it to work and so far have been unsuccessful in getting it to install as well. Some time ago I used it successfully but have had no luck with recent versions. Its too bad there are so many installation problems since its otherwise a very useful package.
