any ideas?

At some point in time (with QuickCheck-2.1.2), the Arbitrary instances for Word8 and Word64 were included in Test.QuickCheck.Arbitrary. Probably around the same time, they were removed from QuickTest.hs in the Crypto package (because one can't have multiple instances for the same type). Seems your QuickCheck is too old for the current Crypto. You can install an older Crypto or a newer QuickCheck. Getting the latest QuickCheck is probably the better way. Cheers, Daniel
