The command is the same and works if you have all necessary tools  
installed.

That's not a warning, that's an error telling you that you don't have  
the necessary "make" command. You must install Apple Development  
Tools (aka Xcode) first. They are present either in the Applications/ 
Installers directory or on the Mac OS X DVD or they can be downloaded  
from ADC. (Please read the FAQ).
