I'd agree and say "gcc" is hardcoded in many places, that's why I believe Apple includes a gcc which is clang on their systems, same for cc. As a question to Lei, I'm wondering why you chose eselect compiler, and not gcc-config to manage the links. In a way, gcc-config is tailored towards gcc, but it does a lot of things also for the environment. With clang, from my experience, you just want it as drop-in replacement for gcc as it doesn't give you too much issues (on Darwin at least). Fabian -- Fabian Groffen Gentoo on a different level
