    # on `GI_TYPELIB_PATH` environment variable. So, when Ide started to depend on Vte, which
    # depends on Pango, among others, GIrepository was unable to find these indirect dependencies
    # and crashed with:
    #
    #     Typelib file for namespace 'Pango', version '1.0' not found (g-irepository-error-quark, 0)

      This package does not pull in the dependencies needed for every
      plugin. If you find that a plugin you wish to use doesn't work, we
      currently recommend running gnome-builder inside a nix-shell with
      appropriate dependencies loaded.
