title: Haskell base-4.x package installation
body: <p>when I try to install this package <a href="http://hackage.haskell.org/package/base-4.1.0.0" rel="nofollow noreferrer">http://hackage.haskell.org/package/base-4.1.0.0</a></p>
  
  <p>by running:</p>
  
  <p>runhaskell Setup configure</p>
  
  <p>I am getting this error:</p>
  
  <p>attempting to use module `System.IO' (System/IO.hs) which is not loaded</p>
  
  <p>Not in scope: `System.IO.stderr'</p>
  
  <p>Not in scope: `System.IO.stdin'
  ghc-6.8.2: panic! (the 'impossible' happened)
    (GHC version 6.8.2 for i386-unknown-linux):
      interactiveUI:setBuffering</p>
  
  <p>Any ideas what might be wrong? Also when I cd to the directory with the files and type ghci I am getting the same error but ghci works in general.</p>
  
  <p>Thanks!</p>
