[BioC] Rgraphviz: .onLoad error

[Kasper Daniel Hansen]

You are using R-2.8.1, so the easiest fix would be for you to upgrade  
to R-2.9. I am not sure we can be too helpfull with older version.

Nevertheless, from
http://bioconductor.org/checkResults/2.3/bioc-LATEST/Rgraphviz/liverpool-checksrc.html
it seems that this version of graphviz was build using 2.21, which is  
a development version (based on the directory name). You will not be  
able to find that archived anywhere. I suggest building from source  
yourself. Or perhaps try Graphviz 2.22 which we still have some  
hiccups with.

So, you should upgrade....
