The file lisp/obsolete/lucid.el has an implementation of extent-at that
may or may not work for you. So try simply
(require 'lucid)
With a 6+ year-old package obviously designed for XEmacs, there may well
be other problems though.
As you can tell from the "obsolete" part, lucid.el has not seen (and
will not see) much attention, so don't be surprised if it doesn't work
right.
