[BioC] installation of Rgraphviz

[Patrick Aboyoun]

One other thing, if you edited your PATH environment variable and had an 
R session running, you need to either restart R or make a system call 
from R that refreshes the environment variables. I googled for the later 
command and couldn't find out what it is. If anybody knows, please share.
