I believe that's the case.

No, you'll need to debug.

No,  building to an particular SDK effectively makes the corresponding MacOSX version
the minimum because we have many dependencies into libraries in /usr/lib; linking against the
stubs in the SDK (or the real library in /usr/lib) sets the minimum version for each.

The easiest way for you to proceed would be to clone gtk-osx and checkout a revision from
before last November and build against those modulesets.
