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,
