I use Debian Squeeze, I have the Debian package cabal-install 0.8.0-1 installed.

    $ git clone git://git-annex.branchable.com/
    $ cd git-annex.branchable.com
    $ cabal update
    $ cabal install cabal-install

This installed: Cabal-1.10.2.0, zlib-0.5.3.1, cabal-install 0.10.2.
No version of monad-control or monadIO installed.

    Command/Add.hs:54:3:
        No instance for (Control.Monad.IO.Control.MonadControlIO
                           (Control.Monad.State.Lazy.StateT Annex.AnnexState IO))
          arising from a use of `handle' at Command/Add.hs:54:3-24
        Possible fix:
          add an instance declaration for
          (Control.Monad.IO.Control.MonadControlIO
             (Control.Monad.State.Lazy.StateT Annex.AnnexState IO))
        In the first argument of `($)', namely `handle (undo file key)'
        In a stmt of a 'do' expression:
              handle (undo file key) $ moveAnnex key file
        In the expression:
            do { handle (undo file key) $ moveAnnex key file;
                 next $ cleanup file key }
    cabal: Error: some packages failed to install:
    git-annex-3.20110719 failed during the building phase. The exception was:
    ExitFailure 1

After I added a depencency for monadIO to the git-annex.cabal file, it installed correctly.
