Rgraphviz neato layout crashes

Hello,

I am having a problem with Rgraphviz

When I try to plot a graph using the "neato" layout, R crashes with a bus error.  I am posting to this list because I can not reproduce this on a Windows machine.  (but I can reproduce it on multiple macs).

This crash can be reproduced just following the example at the beginning of the Rgraphviz vignette.  Has anyone else had this problem?  Any suggested solutions?

Thanks,

Julin

ps OS 10.4.6, Dual 2.5 G5, 4GB RAM.  Graphviz 2.8, compiled from source.  Rgraphviz 1.8, compiled from source.
pps crash happens both from R.app using quartz and from command line or EMACS using X11.
