Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: haskoin-bitcoind-0.3.0 (user goal)
[__1] next goal: haskoin-core (dependency of haskoin-bitcoind)
[__1] rejecting: haskoin-core-0.4.2, haskoin-core-0.4.1, haskoin-core-0.4.0,
haskoin-core-0.3.1, haskoin-core-0.3.0, haskoin-core-0.2.0 (conflict:
haskoin-bitcoind => haskoin-core>=0.4.3)
[__1] fail (backjumping, conflict set: haskoin-bitcoind, haskoin-core)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: haskoin-bitcoind, haskoin-core
