  * Use a more general fix for "cabal install base"
  It's not specific to LHC. Normally we prevent upgrading of base
  since it's unlikely to work and would normally be accidental.
  However when the user explicitly asks to upgrade base then we
  let them do that and they can keep the pieces when it breaks.

    M ./Distribution/Client/Dependency.hs -5 +15
