Yes, I believe that is what we want.  If py-gtk2 requires a different
API/ABI from gtk2 it will also expose a different API/ABI to the
packages that require it.  And those packages need to be rebuilt in
order to adapt to the different API/ABI.  That *is* why py-gtk2 provides
a buildlink3.mk file.  Otherwise the py-gtk2/buildlink3.mk should be
deleted.

Unfortunately the buildlink documentation in pkgsrc.txt is obviously
out-of-date regarding buildlink3.mk usage in cases like this.  Maybe you
want to take it to tech-pkg to clear up that point.

Personally I think it is a waste of time.  If a package provides a
buildlink3.mk file it should be used by other packages that depend on it.
