If it doesn't interfere with my other custom options, catching unsatisfied
requisites is interesting.

But a helpful stack trace is enough for the developer.  Just be sure to say
that it was "this" or "that" requisite that generated the problem and
that's it.  Giving some references on how to fix the problem is a plus.

But if you're going to check everything, you'll end up checking the whole
system at each and every run -- because I might have added / removed
packages since I installed Dabo -- what would give a big performance
penalty.
