cabal: cannot configure Stream-0.4.1. It requires QuickCheck >=2.0
For the dependency on QuickCheck >=2.0 there are these packages:
QuickCheck-2.1, QuickCheck-2.1.0.1, QuickCheck-2.1.0.2 and QuickCheck-2.1.0.3.
However none of them are available.
QuickCheck-2.1 was excluded because IOSpec-0.2 requires QuickCheck <2.0
QuickCheck-2.1.0.1 was excluded because IOSpec-0.2 requires QuickCheck <2.0
QuickCheck-2.1.0.2 was excluded because IOSpec-0.2 requires QuickCheck <2.0
QuickCheck-2.1.0.3 was excluded because IOSpec-0.2 requires QuickCheck <2.0
