Metadata-wise, it's the list of all directories in ${PKG_DBDIR} 
(/var/db/pkg) that do not have a +REQUIRED_BY file, so something simple 
like the following script would work for now, though it will most likely 
not work in the future after the pkg_install rewrite:

#!/bin/sh

: ${PKG_DBDIR=/var/db/pkg}

cd ${PKG_DBDIR}
for dir in *; do
        test -d "$dir" || continue
        test -f "$dir/+REQUIRED_BY" || echo "$dir"
done

        Cheers,
