Doing some testing of per-version requires, I've been looking at this
page quite a bit.
It seems we're missing something to actually apply the default solution,
so "accept default solutions" makes no changes, at the moment. (looks
like we have to do this ourselves with solver_take_solution() ?)
Also, in the dependency problem report, we should identify which of the
possible solutions is the default one, so it's clearer what "accept
default solutions" is going to do.
