The question has come up a few times. I wouldn't mandate that the port
has an upstream gcc (you've got to start mainlining one of them first
after all), but having compilers available for download should probably be
required. It's hard to ask for a particular quality of that gcc port
though, or to expect it to stay available online.

Where did you find the gcc port for score?
