Over-specifies incorrect version 'haskell-directory' for 'warp-static'

When run on
http://hackage.haskell.org/packages/archive/warp-static/0.0.1/warp-static.cabal
the generated PKGBUILD has a dependency on 'haskell-directory=1.0.1.1', which does not build, as the GHC 7.0.2 package provides haskell-directory=1.1.0.0.
The .cabal file only specifies version >= 1.0 && < 1.2 for 'directory'.
