Just as a data point, I saw similar problems ("unknown keyword :group"
errors) that went away after either of `make bootstrap' or
re-evaluating custom.el (and installing non-compiled versions of it).

So either something changed incompatibly about our bytecode, or some
recent versions of emacs must have miscompiled custom.el.
