Hi * -- I haven't found the pkg_add code (it's in Ruby, is it?). But from the behaviour of pkg_add -r, it's safe to say that it doesn't backtrack to resolve dependencies, does it? Like, for instance (a real example), during gnome2 installation on 6.2: warning: 'gstreamer-plugins-gconf-0.10.4_3,2' requires 'gstreamer-plugins-0.10.10,2', but 'gstreamer-plugins-0.10.9,1' is installed pkg_add goes right ahead. It does not com back to deinstalling 'gstreamer-plugins-0.10.9,1' and all its dependencies and _then_ goes back to that point. Isn't this a classic AI backtracking problem? (ok, complete noob opinion here). TIA, Henry
