I started by trying to identify exactly which rule was executed for a 
given .df target that was failing, using "make V=1 ..." to show the 
exact commands that are executed, and then looking at the variables that 
were used.  I was about to start modifying the rule to print out the 
individual variables when I spotted the typo.  When diagnosing a problem 
like this it helps to work directly with the generated Makefile to avoid 
having to regenerate it for every small change.
