Hello.
GTK needs to be initialized before builder can be used

(use-modules (gi) (gi repository))
(require "Gio" "2.0")
(require "Gtk" "3.0")
(load-by-name "Gtk" "Builder")
(load-by-name "Gtk" "init")
(init!)
(builder:new-from-file "app.ui")

Another way to initialize is to use the trio of
application:new, connect, and run.

Hope this helps,
Mike
