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'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/libs/ppc/Rgraphviz.so':
dlopen(/Users/jbyr/Library/R/2.9/library/Rgraphviz/libs/ppc/Rgraphviz.so,

Referenced from:
/Users/jbyr/Library/R/2.9/library/Rgraphviz/libs/ppc/Rgraphviz.so
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?
