My suspicion is that you have something installed improperly.  It sounds
like you might have already, but make sure that you install Rgraphviz with
the '--with-graphviz=/usr/' parameter:
   R CMD INSTALL --configure-args="--with-graphviz=/usr" Rgraphviz

If you've tried that and still no-go, I believe that you don't have
graphviz installed properly.
