Hello, guys. Has anybody tried to install wxhaskell on Snow Leopard?

I followed these instructions: http://www.haskell.org/haskellwiki/WxHaskell/Mac , but got an error: 

src/haskell/Graphics/UI/WXCore/WxcClassesAL.hs:13085:1:
    Unacceptable argument type in foreign declaration: CInt
    When checking declaration:
      foreign import ccall safe "static wxLogWindow_Create" wxLogWindow_Create
        :: Ptr (TWindow a)
           -> CWString -> CBool -> CBool -> IO (Ptr (TLogWindow ()))

Failed to install wxcore-0.90.0.3
cabal: Error: some packages failed to install:

ExitFailure 1

I'm using ghc 7.6.3. I've heard the above problems are related to GHC 7.6.3 being more pedantic about FFI declarations. Is there any way around it?

Thanks
