[BioC] Problem with Rgraphviz on OSX with libgvc

[Jarrett Byrnes]

Nope, this was installed from source.  I'm running R 2.4.1.  The  
error message I gave was after installing graphviz 2.12 from source.   
I have since tried installing graphviz 1.16 from source, as was  
listed in one of the past messages on this listserv, but it did not  
install any libgvc that I can tell.  Is there a particular version of  
graphviz that I should install to make this work?

Also, I installed Rgraphviz from the bioconductor binary using the R  
package manager, including all dependencies.

What version of graphviz do I need to install from source?  Or, will  
the package be fixed soon to reflect the most current version?  Or  
can I just make a symbolic link to the new dynlib to trick the  
package into working (I am not above workarounds)?

Thanks!
