I guess really we'd like the installation process to be painless.

The landing page does say "Users on all platforms must install graphviz; 
  see the README file, available in the source distribution of this 
file, for details." and loading Rgraphviz says, under recent R (2.12 for 
sure; I think 2.11 and maybe earlier), when unable to install,


             Check that (1) graphviz is installed on your system; (2)
             the installed version of graphviz matches '2.20.3'; this is
             the version used to build this Rgraphviz package; (3)
             graphviz is accessible to R, e.g., the path to the
             graphviz 'bin' directory is in the system 'PATH' variable.
             See additional instructions in the 'README' file of the
             Rgraphviz 'source' distribution, available at
