incorrect dependencies on template-haskell

[Brandon Moore]

template-haskell-2.6.0.0 has inaccurate dependencies thatlead cabal-install to attempt to install it on 6.12.3 

The .cabal specifies

    build-depends: base >= 4.2 && < 5,


but assumes TypeSynonymInstances in PprLib.hs

(only true by default after Haskell2010 became default in ghc-7.0.1),

instance Show Doc


and PPr.lhs


import GHC.Show( showMultiLineString )
(added in commit e8d11b1, labeled 4.3.0.0)

It seems the dependency should be at least base >= 4.3,
and either the LANGUAGE pragma or cabal file updated.


If the package isn't meant to be upgraded, should it be on
hackage at all?
