[Haskell-cafe] Trouble building ArrayRef 0.1.3

Hi When I try to build ArrayRef 0.1.3 I get: Control/Concurrent/LockingBZ.hs:159:54: Ambiguous type variable `e' in the constraint: `Exception e' arising from a use of `throw' at Control/Concurrent/LockingBZ.hs:159:54-60 Probable fix: add a type signature that fixes these type variable(s) I am compiling with:

runhaskell Setup.hs build

I run Debian Linux with GHC 6.10.1. Anybody has a solution for my problem? Greetings, Mads Lindstrøm
