I'm thinking of one more option that would be nice: the possibility to
resume `portmaster -r PORT` builds (like the gettext one) without having
to rebuild or manually skip all already rebuilt ports (or
semi-automatically pollute /var/db/pkg with +IGNOREME files using some
primitive shell scripts I hacked together at 1 AM)

An example:

# portmaster -r gettext
now all files in /var/db/pkg/gettext-*/ have fresh modification times T,
and all /var/db/<port-requiring-gettext>/+CONTENTS files have time T.

When portmaster has finished upgrading gettext, it starts with all
dependent-on ports.  If it has finished such a port, all files in
/var/db/<port-requiring-gettext>/ have the same modification time T2
(with T2 newer than T).

The +CONTENTS file for ports which still need to be rebuilt is newer
than the other files (e.g. +DESC), so if portmaster crashes and
restarted, it could skip all ports P for which the following two
conditions hold:
(1) all modification times in /var/db/pkg/P/ are equal (i.e. T2),
(2) those T2 times are newer than T (where T is the modification time of
/var/db/gettext*/* before the mandatory rebuild of gettext itself).

Not having a /usr/local/lib/compat/pkg is cleaner IMO.
