Actually, I misread your question. The instructions for llvm-gcc3 and 
llvm-gcc4 have nothing do with what version of gcc you have installed on 
your system. They refer to which version of gcc was modified to output 
llvm bytecode. You can use whatever gcc is on your system to compile 
either (as long as its not in the FAQ as known not to work).
