Interface file for ShowFunctions not found

[Jose Romildo Malaquias]

Hello.

I am trying to using the ShowFunctions module but
ghc 5.04.1 is not being able to find its interface
file.

A Haskell program to test (t.hs):

------------------------------------------
module Main where

import ShowFunctions

main = print length
------------------------------------------

$ ghc -c t.hs

t.hs:3:
    failed to load interface for `ShowFunctions':
        Could not find interface file for `ShowFunctions'

$ find /usr/lib/ghc-5.04.1/ -name "ShowFunctions*"
/usr/lib/ghc-5.04.1/imports/lang/ShowFunctions.hi

What am I missing?
