There's another package there for the command line tools, too, I think. Maybe someone else can better explain how to set it up so you can properly have what you need, without interfering with what you've already updated via the app store.<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Sep 23, 2019, at 18:35, Richard L.
