On Mac OS X 10.5 it's really trivial, because all necessary tools come  
with the OS - they are on the installation DVD. Just double-click on  
"Xcode Tools" and follow the instructions.

Also please note that detailed instructions on the tools are in the R  
for Mac OS X FAQ (just click on "Help" in the R GUI or go to the CRAN  
Mac OS X page).

Cheers,
