Looks like you've run into the problem with GHC 6.10 extensible extensions:
Storage/Hashed/Utils.hs:33:6:
Ambiguous type variable `e1' in the constraint:
`GHC.Exception.Exception e1'
arising from a use of `catch'
at Storage/Hashed/Utils.hs:(33,6)-(38,58)
Probable fix: add a type signature that fixes these type variable(s)
Storage/Hashed/Utils.hs:50:19:
Ambiguous type variable `e' in the constraint:
`GHC.Exception.Exception e'
arising from a use of `catch' at Storage/Hashed/Utils.hs:50:19-67
Probable fix: add a type signature that fixes these type variable(s)
Maybe it would make sense to use the extensible-exceptions package
so you can use GHC 6.10 exceptions everywhere?
