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
