Conflitos do pacote GHC

Estou tentando compilar o seguinte código com o GHC:

module Test where

import Maybe
import Prelude hiding (null)
import System.IO

null = ()

main :: IO ()
main = putStrLn "Hello, world!"

Se eu apenas correrghc Test.hs, Eu recebo:

Could not find module `Maybe'
It is a member of the hidden package `haskell98-2.0.0.1'.

Então eu tentoghc -package haskell98 Test.hs:

Ambiguous module name `Prelude':
  it was found in multiple packages: base haskell98-2.0.0.1

Não parece certo, mas eu tentoghc -package haskell98 -hide-package base Test.hs:

Could not find module `System.IO'
It is a member of the hidden package `base'.
It is a member of the hidden package `haskell2010-1.1.0.1'.

Então eu tentoghc -package haskell98 -hide-package base -package haskell2010 Test.hs:

Ambiguous module name `Prelude':
  it was found in multiple packages:
  haskell2010-1.1.0.1 haskell98-2.0.0.1

Como faço para compilar esse código? Estou usando o GHC 7.4.1.
