6.10.1 Bug?

According to the hackage page, the Haskell Cryptography Library has a build failure. I couldn't find a bug reference when I searched for milestone 6.10.1 on trac. Should I report it? Has it been fixed? Thanks, Dominic. http://hackage.haskell.org/packages/archive/Crypto/4.1.0/logs/failure/ghc-6....
