I think you're misunderstanding my question.  Aquamacs (as far as I
know) contains code to access Apple's graphical interface
libraries. As far as I know, there is no other implementation of
these.  So according to your theory, when a user runs Aquamacs they
create a derivative work of MacOS X.  If I required the FSF's
permission to distribute a work that links with readline (ignoring
that there is now an alternative implementation), surely I require
Apple's permission to distribute a program that links with their
libraries.  This does not seem like a desirable situation.
