>Description:
	lang/micropython requires python as part of its build process, but
	the pkgsrc Makefile does not specify that, which means that users
	without python already installed will receive an error during make.
>How-To-Repeat:
	In a shell without "python" in your PATH, run "make" in
	lang/micropython, and observe that pkgsrc does not warn you that
	you are missing a build dependency, but the build will eventually
	fail when trying to exec python.
>Fix:
	Users can of course install python manually, but I beleive that
	the package should specify that it uses python as a build dependency,
	through USE_TOOLS or something similar.
