It might be worth while to match your Graphviz with the one Rgraphviz
was built against (2.20) -- the problem is almost certainly at the C
level where this could matter.
Duncan Murdoch has hints here
If 'newbie' means an inexperienced C programmer then this will be a
lot of work. A first step will be to install tools required to build R
from source, and to rebuild Rgraphviz from source with flags set to
generate debugging information. Again Duncan's pages will come in
Hope that helps.
