So I tried to install Rgraphviz 1.10.0 from BioConductor (binaries)  
using the R Package Installer (authorizing R to run system commands  
as root), and this is what I got on the R Console:

trying URL 'http://www.bioconductor.org/packages/1.8/bioc/bin/macosx/ 
powerpc/contrib/2.3/Rgraphviz_1.10.0.tgz'
Content type 'application/x-gzip' length 568248 bytes
opened URL
==================================================
downloaded 554Kb


The downloaded packages are in
	/tmp/RtmptybY6i/downloaded_packages

Then:

 > library(Rgraphviz)
