This will only work, I suspect, if you have the Xcode tools
installed
already, but it should tell you which version of graphviz, your
Rgraphviz is linked against.
No such luck. AFAIK, I have Xcode (I downloaded the latest developer tools recently), but:
rglibs <- system.file("libs/Rgraphviz.so", package="Rgraphviz")
system(paste("otool -L", rglibs))
rglibs

Sorry, looks like the Rgraphviz.so or equivalent is in a different place in the Rgraphviz binary. Can you take a look at the installed package directory ( system.file(package="Rgraphviz") ), find the .so or .dylib and try the otool thing again (from R).
The problem definitely occurs on PPC.

In other words, nothing.
I found Rgraphviz.so here:
/Library/Frameworks/R.framework/Versions/2.3/Resources/library/
Rgraphviz/libs/ppc/Rgraphviz.so
There are over 1200 files *.dylib on my disk.
