Hi all,

I have released, and of cabal-install, after a
fix was found for #3003 <>:

If you encounter an error similar to the following when running
`cabal install cabal-install` or 'cabal install Cabal':

    Duplicate instance declarations:
      instance Binary Version
        -- Defined at
      instance [safe] Binary Version
        -- Defined in ‘binary-’

try running 'cabal install -j1 Cabal' to work around the 'binary-0.8'
compatibility issue.
