Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: tasklite-0.3.0.0 (user goal)
[__1] unknown package: tasklite-core (dependency of tasklite)
[__1] fail (backjumping, conflict set: tasklite, tasklite-core)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: tasklite, tasklite-core
