[Haskell-cafe] Access to Oracle database from Haskell

Is there a way of accessing a remote Oracle database by one of the common Haskell database interfaces (HaskellDB, Takusen, etc.) ? I tried to get unixODBC and Oracle's Instant Client running on a Linux machine, but I'm trapped in the notorious error: $ isql USER -v [IM004][unixODBC][Driver Manager]Driver's SQLAllocHandle on SQL_HANDLE_HENV failed [ISQL]ERROR: Could not SQLConnect This error message is discussed in various web forums, but there seems to be no systematic way to track down the problem. So I wonder whether there is another way to access the Oracle data base from Haskell.
