Really, that's not a syntax I've ever seen before, I've no idea how that
works, all on the same line, sure, but on the next line like that, odd!.
I would have thought that this would have caused "export PYTHON=
$(PYTHON)" to be run it its own new subshell which would immediately
exit.

Anyway, I guess if it works we might as well use this version...
