But we don't have that now. For example dns/py-dnspython can create 
py27-dnspython, py33-dnspython, py34-dnspython, py35-dnspython - four 
different packages from one origin, one Makefile.
OK, I noticed now that slave port for py3 was added "recently" but even 
this slave port can create 3 different packages according to what 
default version of python 3 is installed.

Another thing is that portmaster and portupgrade are not well maintained 
and I think ports / ports framework evolution should not be slowed down 
because of "3rd party" utilities. Or we will end up with adding tons of 
directories and small files just to create endless pile of slave ports.
