[BioC] installation of Rgraphviz

[Yanwei Tan]

Dear all,

I am writing to consult everyone about installing package Rgraphviz on 
Mac 10.5.8. Here I met a problem of install.  Following is the commands:

 > source("http://bioconductor.org/biocLite.R")
 >     biocLite("Rgraphviz")
Using R version 2.10.1, biocinstall version 2.5.10.
Installing Bioconductor version 2.5 packages:
[1] "Rgraphviz"
Please wait...

Does anyone give me some hints about how to install this package?  Or 
should I try download the package source? Let me know if extra info is 
needed. With many thanks in advance!
