They can coexist.  The steps I use are to install both into separate 
directories.  Don't add either bin dir to your path.  Then create (in some 
directory in your PATH) symlinks to both trees.  I have llvm-gcc/llvm-g++ 
symlinked to llvm-gcc4 and llvm-gcc3/llvm-g++3 symlinked to the llvm-gcc3 

Seems to work for me, YMMV,
