I had this exact same problem yesterday.  I dealt with it by remerging all
packages with a "required by" line.  In your case, that would wine (in my case,
it was wine, llvm, and octave).

However, there were some commits today related to this, so maybe resyncing and
trying again will help.

The funny thing is that the day before, on another computer, portage resolved
the blocker automatically by re-emerging llvm and octave (slot-operator ("rR")
type re-emerge).
