TIA.
The solution to this and similar problems are always, as pointed out by specific solutions in this thread by others, to turn your dependency formula into conjunctive normal form (CNF) [1], which is always possible, though possibly ugly, as you observed. Note that if you want to go the "wishlist bug" path however, the bug should not be against dpkg, but rather against policy. The reason being that policy currently only allows dependency formulae in conjunctive normal form. Cheers.
