Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: gargoyle-postgresql-0.2.0.0 (user goal)
[__1] next goal: gargoyle (dependency of gargoyle-postgresql)
[__1] rejecting: gargoyle-0.1.1.0 (conflict: gargoyle-postgresql =>
gargoyle==0.1.1)
[__1] skipping: gargoyle-0.1 (has the same characteristics that caused the
previous version to fail: excluded by constraint '==0.1.1' from
'gargoyle-postgresql')
[__1] fail (backjumping, conflict set: gargoyle, gargoyle-postgresql)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: gargoyle-postgresql, gargoyle
