That's a start, but it gives an overly-broad approach, saying that
anything linked to the ncurses library has to be recompiled.

The ABI change is just to the (upper-level) curses interface.
Most of the programs you'll have in ports use the (lower-level) termcap
or terminfo interfaces.

For example gettext uses terminfo (not curses).

Curses applications use initscr or newterm (nm helps).
I have a script which uses nm to tell me which interface is used.

Actually, in my own ports, I don't see any which would be affected,
since all of the curses applications are the utilities for ncurses
(or for my testing of ncurses).

Here's an example of what it tells me
(n5==ncurses5, tc=termcap, ti=terminfo):

ti	bison
n5*+ti	captoinfo
n5*+ti	captoinfo6
n5*+ti	clear
n5*+ti	clear6

n5+ti	dialog4ports
n5*	dittot
n5*	dittotw
tc	info
n5*	infocmp
n5*	infocmp6
n5*+ti	infotocap
n5*+ti	infotocap6
n5	lynx
n5	lynx-bw
n5	lynx-cs
s	lynx-slang
n5	lynx-wide
ti	msgattrib
ti	msgcat

ti	msgfilter
