[R-SIG-Mac] Rgraphviz installation problem

[Simon Urbanek]

Michael,

first, you may want to use the Rgraphviz binary from Bioconductor as  
it saves you all the hassle (see http://r.research.att.com/ at the  
bottom for the corresponding Graphviz build).

As of your error, it seems that you have a mismatch of various  
graphviz versions on your machine, one of which is not working - the  
one in /usr/local. Building graphviz is not quite painless so I would  
really suggest using the binary above instead.

Cheers,
Simon
