Hrm, not quite what I had in mind...  I don't want to misrepresent that
a port was built against a newer version of a dependency.  What I was
hoping for would be that a port when reinstalled would not list both the
current version of a dependency as well as a previous version of the
same origin (which it aquired via the +CONTENTS of some other direct
dependency).  It should only list the currently installed version of
that origin.

That way it is still possible to determine that the interim port was
built against an older version.  I just want the +CONTENTS file to
accurately list the versions that a given port was built against.
