I am confused why it was trying to run cmcat, which it only should have done if
$(NAME).cm didn't exist.  Since $(NAME).cm is part of the sources, I don't
understand why it was missing.

Agreed.  I am now fixing the problem.

The terminating ";" is there for some versions of BASH that barf without it.
