[R-SIG-Mac] Rgraphviz leads to crash with 2.7.0 (development) on Leopard

[William Revelle]

Hi,

  I have started testing out the 2.7.0 development version  on a 
MacBookPro running Leopard (10.5.1) to see if my psych package works.

Most of what I do seems to work (and I think the graphics look even 
better than 2.6.1), but Rgraphviz causes a complete crash when trying 
to load it. This is independent of my package in that just loading 
Rgraphviz leads to a crash.

Here is the complete error report:
