installing Rgraphviz

Jarrett,
This is a Bioconductor related question and really should be addressed 
on the Bioconductor mailing list. The sort answer is if you are 
running on a Mac OS X 10.4 (Tiger) box, you will need to build both 
graphviz and Rgraphviz from source in order to use the package. If you 
are running on a
Mac OS X 10.5 (Tiger) box, continue reading.

The issue is that graphviz.org distributes their latest version of 
Graphviz for Mac OS X 10.5 (Leopard) only and we use that when we 
build our mac.binary.leopard version of Rgraphviz. I am guessing that 
you are using the cross Mac OS X pre-compiled version of R, which uses 
the mac.binary build of the package from our Mac OS X 10.4 (Tiger) 
build machine that has an old (unmaintained) version of graphviz on 
it. I recommend that all Bioconductor users running on leopard to use 
a leopard-only build of R available at http://r.research.att.com/, 
since that is what we use on our build machine. These leopard only R 
binaries download, via biocLite, mac.binary.leopard versions of the 
packages that are produced by our Leopard machine. These leopard only 
binaries have the added benefit of 64-bit Intel support so end-users 
don't have to build their own packages once they leave the 32-bit world.

I'm attempting to install Rgraphviz from bioconductor.  I downloaded 
the stablemac version from http://www.graphviz.org/Download_macos.php 
and used biocite to install Rgraphviz after installing bioconductor.  
However, when I attempt to load Rgraphviz, I get the following error.

Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared library 
'/Users/jbyr/Library/R/2.9/library/Rgraphviz/libs/ppc/Rgraphviz.so':

  Referenced from:

Error: package/namespace load failed for 'Rgraphviz'


I went to look for libgvc.3.dylib, and there in /usr/lib found 
libgvc.5.dylib .

Is the answer here to install an older version of graphviz? If so 
which one?  Or can Rgraphviz be made to work with my existing 
installation of graphviz?
