Tool to check for non-default options for installed ports

[Kevin Oberman]

I should just write this as it looks very straight-forward but I'm lazy and
hate reinventing wheels.

On my development system I build from ports. An on-going issue is that
ports frequently change options from non-default to default and I never see
the change. The result is that every now and then a port won't build due to
a change or a port runs with reduced capabilities or performance when a new
option becomes the standard.

Looking at the DEFAULT_OPTIONS in the port Makefile and comparing them with
saved config is trivial and I suspect a tool for this has probably been
written several times.

Thanks!
