---------------------------------+------------------------------------------
 data-accessor-template-0.2.1.3 has flags in the cabal file on template-
 haskell versions, which makes it broken for cabal-install on ghc-6.12:

 cabal-install tries to install template-haskell-2.3, which fails (and it
 can't be expected to succeed because TH is integrated into ghc due to
 quotes)

 You can work around the build failure with:

 {{{
   cabal install data-accessor-template --constraint='template-haskell >=
 2.4'
 }}}

 cabal-install ought to know that template-haskell isn't something it
 should install (as it does with base).
