[Haskell] cabal-upload build problem

[Paul Johnson]

I want to upload a package to Hackage.  I tried installing cabal-upload, 
but got the following error:

! Preprocessing executables for cabal-upload-0.2...
! Building cabal-upload-0.2...
!
! src/CabalUpload.hs:7:7:
!    Could not find module `Distribution.Compat.FilePath':
!    it is hidden (in package Cabal-1.1.6)


I tried "ghc-pkg expose Cabal-1.1.6" without success.

I have ghc-6.6 installed on Linux (Fedora Core 6), including Cabal-1.1.6.

(BTW I know I will also need a user id and password.  That was going to 
be my next step).

Paul.
