Resolving dependencies...
cabal: Could not resolve dependencies:
trying: silvi-0.1.0 (user goal)
next goal: chronos (dependency of silvi-0.1.0)
rejecting: chronos-1.0.1, chronos-1.0, chronos-0.4, chronos-0.3,
chronos-0.2.0, chronos-0.1.0 (conflict: silvi => chronos>=1.0.2)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: silvi, chronos
