Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: ppad-secp256k1-0.5.2 (user goal)
[__1] next goal: ppad-fixed (dependency of ppad-secp256k1)
[__1] rejecting: ppad-fixed-0.1.2 (conflict: ppad-secp256k1 =>
ppad-fixed>=0.1.3 && <0.2)
[__1] skipping: ppad-fixed-0.1.1, ppad-fixed-0.1.0 (has the same
characteristics that caused the previous version to fail: excluded by
constraint '>=0.1.3 && <0.2' from 'ppad-secp256k1')
[__1] fail (backjumping, conflict set: ppad-fixed, ppad-secp256k1)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: ppad-secp256k1, ppad-fixed
