	Let me be more precise.
	I have a list of 110 installed ports flavored "py27-".
	For each port I want to know:

	a) according to the Makefile, is it possible to build this with
		python-37?  (Or even -36?) 
	b) will doing so break any port for which this port is a dependency?

	I understand the only way to answer (b) may be by trial-and-error;
fair enough.  But if I can identify all those with no dependants
... that would be a start.
