Most likely your problem is that you're using cctools that are too  
old.  Are you using cctools-622.3 or later?  Generally, every time  
Apple releases a new cctools, you need to upgrade to it.

You'll also need /usr/bin/dsymutil.  You can fake this by symlinking  
it to /bin/true.

Mike was considering simply declaring that GCC 4.3 won't work on Mac  
OS 10.3.  10.3 is quite old now, and there will be very few users by  
the time that 4.3 is released.
