 I was trying to compile haskell-src-1.0.1.4 with ghc-7.1.20110213 and got
 this error message:

 {{{

 Implicit import declaration:

       it was found in multiple packages: base haskell98-1.1.0.0

 ExitFailure 1
 }}}

 I don't know if this is specific to ghc-7.1.20110213 or some other 7.x.x
 versions are affected (it did compile on 6.12.3 though). Adding --ghc-
 option="-hide-package haskell98-1.1.0.0" seems to have no effect.
