    name = "dhall-compiled-package.nix";

    buildCommand = ''
      # Dhall requires that the cache is writable, even if it is never written to.
      # We copy the cache from the input package to the current directory and
      # set the cache as writable.
      cp -r "${dhallPackage}/.cache" ./
      export XDG_CACHE_HOME=$PWD/.cache
      chmod -R +w ./.cache
