upgrading Cabal in ghc-6.4.1-pre

[Serge D. Mechveliani]

Dear Cabal developers,

I have the following problem with upgrading Cabal in
                             ghc-6.4.1.20050806-i386-unknown-linux.

First, I have installed this  ghc-6.4.1-pre binary  to my home
directory.

  > which ghc
  /home/mechvel/ghc/6.4.1-aug-1/binary/inst/bin/ghc

Then,                   ghci -package Cabal
reports of  Cabal-1.0.

I need to upgrade Cabal to 1.1.1. 
To do this, I unfold new Cabal to  
                               /home/mechvel/ghc/cabal/1.1.1/cabal/
Then I do
          cd /home/mechvel/ghc/cabal/1.1.1/cabal/

and edit in  GNUmakefile  the two lines to
  
  PREF=/home/mechvel/ghc/cabal/1.1.1/inst

  HCBASE=/home/mechvel/ghc/6.4.1-aug-1/binary/inst/bin/

in order to install new Cabal to  /home/mechvel/ghc/cabal/1.1.1/inst
.
Then I command

  make setup
  ./setup configure --prefix=/home/mechvel/ghc/cabal/1.1.1/inst
  ./setup build
  ./setup install --user

Then,    ghci -package Cabal
reports
---------------------------
               GHC Interactive, version 6.4.1.20050806, for Haskell 98.

--------------------------------------------------------

Then I go to my application  Dumatel  and try to make it with GHC:


~/dm/1.03/dm/source> runhaskell Setup configure --ghc --prefix=$dmSource/inst

--------------------------------------------------------------------

This looks all right.

   runhaskell Setup build

Could not find module `Prelude':
  it is a member of package base-1.0, which is hidden
  (imported from Dumatel.hs)
---------------------------------------------------

And this differs from what it was with Cabal-1.0.
I does not want to compile things.

How to fix this, please?
