The distribution zip is under 20MB. Even with vim, git and Python, it's still just 60MB. The GNU toolchain pushes it much larger, and it's not part of the early education curriculum I'm proposing. C compiling is something I'll be working people to after several positive experiences with Python. Also, it's just one repository command away from being installed, so I figure I'll add it as one of those menu options that you get presented with after startup.
