[BioC] can't load Rgraphviz under BioC 2.2 devel version

[Florian Hahne]

It is actually the graph package that fails to load, and I think the 
error message is fairly explicit:
You need at least version 7.0.0 of the iconv library, but installed on 
your sytem is version 5.0.0. Try updating libiconv and see if that helps.
And don't ask me why the graph package needs character encoding 
conversion, I have no clue :)
Cheers,
Florian
