[BioC] installation of Rgraphviz

[Patrick Aboyoun]

Ravi,
As Fraser mentioned, graphviz is a moving target that we often have 
difficulty linking into. The Windows binary BioC 2.4 (R 2.9) package on 
bioconductor.org has been build using a Windows build of the previous 
stable release of graphviz (version 2.20.3.1) located at

http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.1.msi

I have tried using a Windows build of the current stable release of 
graphviz (version 2.22.2)

http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.22.2.msi

but I had trouble linking into the graphviz container data type library 
(cdt.dll). I was experiencing an unresolved symbol in the Microsoft 
Visual C++ run-time library (msvcrt.dll) related to object destruction 
on a machine running Windows Server 2003 (with Microsoft Visual Studio 
2008 Express Edition installed). Time permitting, I'll look into where 
in the cdt.dll graphviz library things are going awry. If others have 
success with the current stable release of graphviz, please share with 
the group.


Cheers,
Patrick
