Actually it would be useful to have this functionality somewhere.  I
recently spent a couple of hours trying to track down a circular
dependency I had introduced via a bsd.port.mk patch.  The main symptom
was that the make_index script would just go into a loop and exhaust
memory.  I ended up finding it by adding all sorts of debugging
printfs to the perl script, but this was pretty ugly.
