Does that line in the real Makefile begin with a tab? It must.

Why is it so roundabout about $(DEPS)/$(FILES)? The target *actuall*
depends on different files than those declared in the sources list!

What does $(DEPS) (and $(FILES)) contain?

This is what your Makefile does, BTW:

  grep ^keywords keylist.txt ... > keylist.txt

Try it with this instead (rename keylist.txt to key.list), but make sure
you have at least one file ending in .txt in that directory first!):

KEYLIST := key.list
FILES := $(wildcard *.txt)

$(KEYLIST): $(FILES) ; grep '^keywords' $^ > $@
