Comment(by guest):

 Thanks for answering!

 Sounds complicated. I guess, good error reporting for unsuccessful
 constraint solving is a big subject in its own right.

 BTW: Increased verbosity (-v3) results in a message containing this:
 [_39] fail (unknown package: bogus)
 [__0] fail (backjumping, conflict set: bogus, foo)
 Which is what I would expect from cabal-install without increased
