Thomas Dickey wrote about tracking upper vs. lower interface
distinctions to cut down on what needs to be built.

The below does not go that direction but does cut down the list
to ports directly involving /lib/libncurses[^ ]*\.so\.8 :

# find /usr/local/*bin* /usr/local/lib* -type f \
| xargs ldd -f '%p %A\n' 2>&1 | grep "^/lib/libncurses[^ ]*\.so\.8" | cut -w -f2 \
| xargs ldd -a | egrep '(^/.*:$| /lib/libncurses[^ ]*\.so\.8 )' \
| grep -B1 " /lib/libncurses" | grep "^/.*:$" | sed -e's;:$;;' \
| xargs pkg which -q | sort -u | more
dialog4ports-0.1.6
gdb-8.3.1
gdbm-1.18.1_1
gnuplot-5.2.8
libedit-3.1.20191211,1
libtextstyle-0.20.1
llvm10-10.0.0.r2
llvm80-8.0.1_3
python37-3.7.6
readline-8.0.1
ruby-2.6.5,1
sqlite3-3.30.1,1
texinfo-6.7_1,1
xterm-353_1

So, for example, "bison-3.5.2,1" is not listed because only its use
of "libtextstyle-0.20.1" brought in a ncurses library use overall.
The "libtextstyle-0.20.1" is listed.
