Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: hsec-sync-0.1.0.0 (user goal)
[__1] next goal: hsec-core (dependency of hsec-sync)
[__1] rejecting: hsec-core-0.1.0.0 (conflict: hsec-sync => hsec-core>=1.0 &&
<2.0)
[__1] fail (backjumping, conflict set: hsec-core, hsec-sync)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: hsec-sync, hsec-core
