A comment on Beating the Arc Challenge in Haskell.

Re:Beating the Arc Challenge in Haskell by albertcardona on Saturday December 19, 2009 @09:25AM (#1004780)
I am trying to run the haskell code in Ubuntu 9.10 with ghc6, but:

  Failed to load interface for `Control.Applicative.Error':
      locations searched:
        Control/Applicative/Error.hi
        Control/Applicative/Error.hi-boot
Which library am I missing? apt-file search for Control/Applicative/Error.hi yielded none.

Help appreciated from all HN-reading haskell'ers.

do a "cabal install applicative-extras", that should help.
