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. Kris
