[R-SIG-Mac] Rgraphviz installation problem

[Rob J Goedman]

I  see the exact same behavior. In this example, plot(g1, "dot")  
works fine, but as soon as "neato"
or "twopi" is selected:

Happens both with the the binaries from Simon's web site + the  
Rgraphiz binary and if I build
them from sources.
