NOTE: Most users don't need to even look at the tools page! It is  
there mainly to allow experienced users to pick and choose some  
optional tools they may like. If you are not sure that you need any of  
it, the answer is you don't. The first two items (gfortran and tcltk)  
come bundled with R so you likely have them already and the devpack is  
only for people that want to build their own R and re-create the  
environment that the CRAN build machine is using.

No, use the same procedure you used for the R installation:
curl -s http://cran.r-project.org/bin/macosx/tools/devpack4-darwin8-bin4.tar.gz 
sudo tar fvxz - -C /
