The following finds "libncurses[^ ]*\.so\.8 => not found " examples
from ldd and reports on the port that got such:

# find /usr/local/*bin* /usr/local/lib* -type f \
| xargs ldd -a 2>&1 | egrep '(^/.*:$|libncurses[^ ]*\.so\.8 => not found )' \
| grep -B1 " not found " | grep "^/.*:$" | sed -e's;:$;;' \
| xargs pkg which -q | sort -u | more
dialog4ports-0.1.6
gdb-8.3.1
libedit-3.1.20191211,1
llvm10-10.0.0.r2
python37-3.7.6
readline-8.0.1

(I created a context to run the above sort of command in,
a context with a few examples to find.)
