A slightly better version. This one takes account of package versions:

check-depends() {
        for DEP in  $(bmake show-depends|cut -f1 -d":");
        do
                pkg_info -qE   $DEP && echo $DEP found: $(pkg_info -E   $DEP)\
                        ||  echo "$DEP: not installed";
        done

}

$ cd pkgsrc/current/pkgsrc/www/liferea/
$ check-depends

I'm trying to make it work in sh/dash but it won't.
