[Haskell-iPhone] Installing aeson as a dependency with cabal-ios

Hi, I’m attempting to install aeson as a dependency for another library with cabal-ios. I’m somewhat confused because I believe I’ve installed aeson (after removing the template haskell), but when I try to build my library, it attempts to install aeson again. Does anyone have any suggestions? You can find the build logs here http://lpaste.net/7956551478481518592. Thanks! James
