I had simply left out 'use_clause' in the grammar for this case. Patch:

If you have the old ada-mode loaded when you install the new one, then
you have to restart; Emacs does not have a way to unload a package.
It's actually best to restart _before_ installing the new package (and
don't load anything before installing); that way, the byte compiler has
the cleanest environment. This only matters if I've made a mistake in
the 'require' structure somewhere, but as we have seen, sometimes I need
help finding those :).
