The Rgraphviz package provides an interface to AT&T's graphviz
library.  It looks to me like you have not installed graphviz on your
system.

[I think this is also a bug in the configure script for Rgraphviz
which should fail with a clearer error message instead of trying to
build]

You can download graphviz from here: http://graphviz.org/
