Simon, A followup to the Rgraphviz issue and why I think installing X-Code solves at least one problem with getting it to work
On a G4 Powerbook I updated R to 2.5.0 patched. I then went to bio-conductor and downloaded Rgraphviz and all the associated packages. Then installed graphviz 2.1.2 from http://r.research.att.com/. However, Without X-Code installed, when I try library(Rgraphviz) I get the following error message: library(Rgraphics) Error in library(Rgraphics) : there is no package called 'Rgraphics' Loading required package: graph Loading required package: geneplotter Loading required package: annotate Loading required package: Biobase Loading required package: tools Welcome to Bioconductor Vignettes contain introductory material. To view, type 'openVignette()'. To cite Bioconductor, see 'citation("Biobase")' and for packages 'citation(pkgname)'. Loading required package: lattice KernSmooth 2.22 installed Copyright M. P.

(And it is well worth loading for it makes some very nice graphs). This was done using R version 2.5.0 Patched (2007-04-25 r41315) (just installed R 2.5.0 today on the G4 power book that had this problem. ) As I said yesterday, when my students or I installed X-Code on G4s, G5s, or MacBook Pros, then we were able to load Rgraphviz. Once loaded, it works like a charm.
