I think Simon is the one building the Rgraphviz binary so he might be
able to shed some light on where it is expected to work (with which
version of R and whether a graphviz lib is required or not).

If you installed a recent graphviz, then there is no dotneat-config
script.  Instead, for the autoconf tools to work, you need the
pkg-config program installed and PKG_CONFIG_PATH set appropriately
(/blah/lib/pkgconfig).

But it should also work to pass the --with-graphviz configure option.
Something like:

R CMD INSTALL --configure-args='--with-graphviz=/blah/graphviz' \
    Rgraphviz_x.y.z.tar.gz

So I would try this first.  I would also try with the devel version of
Rgraphviz.
