I install HLint via cabal (output http://hpaste.org/88021)

To check if it was working I used following code

fun1 :: Int -> String
fun1 1 = "hell"
fun1 2 = 3

and ran HLint on it
$ ~/.cabal/bin/hlint hlint_test.hs
No suggestions

and it ouputs no suggestions
any ideas?

Additionally
$ ~/.cabal/bin/hlint -v
HLint v1.8.45, (C) Neil Mitchell 2006-2012
