I agree with Chris. But to comment on your specific question: it looks 
to me as if you don't have Apple's developer's tools (a.k.a. XCode) 
installed -- it can't seem to find the C compiler (gcc). To build PIL 
from source you have to have the developer's tools installed. Then you'd 
have to build various unix libraries from source. It's a lot easier to 
use the existing binary if you can.
