A temporary hack is to also check /var/lib/emacsen-common/installed-flavors
presence (see #268466),
if [ "$1" = "configure" ] && \
[ -x /usr/lib/emacsen-common/emacs-package-install ] && \
[ -e /var/lib/emacsen-common/installed-flavors ]
then
/usr/lib/emacsen-common/emacs-package-install #PACKAGE#
fi
Note that this is a hack and was not originally designed to check that
emacsen-common is configured, but should work with current setup. This
will surely need changes once Rob redesign is done and in effect, but system
may need changes anyway.
Also note that this means you must add that code explicitely and do not rely
in dh_installemacsen.

If you only add few lisp files I would temporarily use above hack and wait
for Rob re-design to decide what it allows and what to do. I personally
dislike packages with little lisp needing to create a new package just for
that lisp.
