What you need is to check if '+REQUIRED_BY' file exists. (For finer
control, also check if it is empty or not.) If file does not exist
(or is empty), then there is no registered dependency.
#!/bin/sh
pkgdb=/var/db/pkg
for p in $pkgdb/*
do
[ -f "$p/+REQUIRED_BY" ] || { echo "$p" | sed -e "s!^$pkgdb/!!" ; }
done
