You probably want to strip out the stuff in /usr/share/mk which should
not have any impact on port dependencies, but to be strict you should
treat changes to /etc/make.conf and bsd.port.mk as requiring a rebuild
of the full index.  bsd.sites.mk can be ignored too.

Also you need to think about the case of variables being set in the
environment but not in make.conf - either you have to recognise them
somehow (difficult), or (better) you have to build the index with a
clean environment since otherwise you'll get undefined results
(e.g. if someone does a partial update after having set WITHOUT_GNOME
in the environment of that shell, they'll get a wacky index that may
not be self-consistent).

There's also the problem of ports that auto-detect their dependencies
based on installed files; this is difficult to solve because the
trigger is some random file on the system.  If someone builds index,
installs such a 'trigger port', and then does an index update, their
incremental index won't be the same as if they rebuild it from
scratch.
