[Haskell-cafe] Problems installing Data.Encoding package

Hello, I'm stuck at trying to get Data.Encoding package functional. Cabal gives the following error message: cabal install encoding Resolving dependencies... /var/folders/xc/jnh69_cx1n32n1qwkgfrlc100000gq/T/encoding-0.6.620435/encoding-0.6.6/dist/setup/setup: /var/folders/xc/jnh69_cx1n32n1qwkgfrlc100000gq/T/encoding-0.6.620435/encoding-0.6.6/dist/setup/setup: cannot execute binary file cabal: Error: some packages failed to install: encoding-0.6.6 failed during the configure step. The exception was: ExitFailure 126 What could be done here? I'm on MacOS Lion, ghc v. 7.0.4 Regards, Peteris
