I know variants of this have been answered a few times, but thus far  
I've had no luck:

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.so, 6): Library not loaded: /usr/local/lib/libgvc.3.dylib
   Referenced from: /Users/jbyr/Library/R/2.9/library/Rgraphviz/libs/ 
   Reason: image not found
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?
