Mac GUI for 2.9.0 alpha and Rgraphviz

Dear Simon and other Mac Gui developers,

I have been testing the psych package for 2.9.0 and have found an  
unrelated  problem with the GUI when it is interacting with Rgraphviz.

If I run R.app directly from the X11 window, I can load and run  
Rgraphviz with no problem.

But, when I try loading the Rgraphviz package by

library(Rgraphviz)  , the Gui crashes;

*** caught segfault ***
address 0x656c7574, cause 'memory not mapped'

Traceback:

my sessionInfo is

R 2.8.1 GUI 1.27 Tiger build 32-bit (5372)


(I have the identical problem with
R.app GUI 1.28-devel (5355 Leopard build 32-bit),)

In that this does not happen in the R.app itself, but with the Mac  
Gui, I am reporting it here.

Thanks again for the wonderful GUI.  My students who use PCs are  
very jealous.
