I got to this point and ran into an error: Makefile:2: *** missing separator. Stop.

Ok I'm just giving you a hard time, and you mention right after the existence of "tab indented" so whatever. Still it's one of the things I detest on an aesthetic level about make, even if my editor has special syntax support for makefiles to handle this archaic requirement of actual tabs without me ever having to worry about it in practice.
