Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: immutaball-core-0.1.0.4.1 (user goal)
[__1] next goal: wires (dependency of immutaball-core)
[__1] rejecting: wires-0.2.1 (conflict: immutaball-core => wires>0.2.1 &&
<0.3)
[__1] skipping: wires-0.2.0, wires-0.1.0 (has the same characteristics that
caused the previous version to fail: excluded by constraint '>0.2.1 && <0.3'
from 'immutaball-core')
[__1] fail (backjumping, conflict set: immutaball-core, wires)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: immutaball-core, wires
