[Bioc-devel] Rgraphviz error in Bioconductor 2.2 build for windows

[Martin Morgan]

This is usually a symptom of a version mismatch between the version of 
graphviz used to build Rgraphviz, and the version of graphviz found when 
Rgraphviz is loaded.

My guess is that you have graphviz 2.18 installed, but need 2.16.1 to 
match the version used to build windows Rgraphviz available through 
biocLite.

Here's the link to the correct graphviz
