It means that you didn't follow the instructions (it says that you  
don't have "make"). You need to install Apple's Xcode development  
tools in order to compile anything. Xcode is on the Mac OS X  
installation DVD and can also be downloaded from Apple. Please read  
the R for Mac OS X FAQ it has detailed instructions.
