Hi guys,

I'm new to haskell and I'm trying to make some calls to static methods of the Microsoft .NET framework with GHC 6.10.2 but I'm getting the follwoing error:

GHC error in desugarer lookup in main:Main:
Failed to load interface for `GHC.Dotnet':
There are files missing in the `base' package,
try running 'ghc-pkg check'.
Use -v to see a list of the files searched for.
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.2 for i386-unknown-mingw32):
initDs IOEnv failure

My haskell code is this:

{-# LANGUAGE ForeignFunctionInterface #-}

module Main where

import Prelude
import Foreign

foreign import dotnet "static foo" foo :: Int -> Int

main = do print (foo 5)

To build the code above I'm doing like this: ghc -fvia-C Main.hs

Am I forgeting something? Does this version of GHC supports FFI for .NET?
