[Haskell-cafe] ffmpeg-tutorials fails to build

Hi, Info: ghc 6.12.3 (installed from haskell plataform) Mac os x snow leopard 10.6.4 ffmpeg instaled from ports - ffmpeg @0.6.1 hs-ffmpeg 0.3.4 - installed from cabal-install When I try compile this package, I get this erros: I'm build it to get a starting point to use hs-ffmpeg. Anyone have the same problem? Any ideias? Thanks, Victor
