gettext was added to the lode and it "just works". Updating lode and
rerunning its setup will add gettext for anyone who had already pulled
lode before the changeover. It might be worth mentioning that gettext
is only needed if --with-lang is used, so ./configure && make doesn't
need it, so most developers probably *don't * need it, but adding that
info the build instructions seemed likely to be more confusing than
not.
