I think it would be a framework change.
not  so much a per-port change.
By default, when the variable is set you take the list of options for 
the package, and set them all to 'unset'.

The only packages that would need work would be those for which that 
is not a valid configuration, in which case you would supply some 
precanned list of options to set to unset (or similar)  e.g. 
MIN_SETTINGS="bla foo bar"

the point is that if I'm including a port becuase it's just a prereq. 
then I probably want almost no options set..  The port itself can 
probably know what options are likely to be needed by things that need 
it adn can possibly supply a sensible setting but if it doesn't it 
might be possible to just do it automatically. It's ridiculous that a 
single small port can pull in python, perl and TCL (I forget which it 
was) along with some 40 or so other packages.

Another thing that might be good woudl be a way to tell ports "remove 
all the ports that were just build dependencies".
