so libtool makes it
        libncurses.6.1.4.dylib
or
        libncurses.6.0.4.dylib
?

so I see - the rules I've got for darwin use $(NCURSES_MAJOR) and
$(NCURSES_MINOR) rather than $(ABI_VERSION).  I think I have enough
information to be able to make libtool do the expected thing on my next
patch -- I'll add that to my to-do list.

Note that in general it's not possible to make the versions match up,
since libtool uses its own convention for version numbers.
