Oh that was easy. I had to do this:

[danbst at localhosted:~/nixpkgs]$ nix-env -f .  -iA haskellPackages.pipesCore
or build with
[danbst at localhosted:~/nixpkgs]$ nix-build -A haskellPackages.pipesCore

But dependency hell was not gone.


   1. pipes-core-0.1.0: dependency
   "base-4.5.0.0-f76ceb9607ba9bd4fcfb9c7b92d8cfe1" doesn't exist (ignoring)
   2. pipes-core-0.1.0: dependency
   "categories-1.0.3-e9ab00168a7d0fdacafd64b31a5e1100" doesn't exist (ignoring)
   3. pipes-core-0.1.0: dependency
   "lifted-base-0.1.1-51e1520336adbfccd889e58e684c89a1" doesn't exist
   (ignoring)
   4. pipes-core-0.1.0: dependency
   "monad-control-0.3.1.3-a94da65cc1c2dcd38097f790cd885593" doesn't exist
   (ignoring)
   5. pipes-core-0.1.0: dependency
   "transformers-0.3.0.0-f2303dfef836518cc2f6901210442e10" doesn't exist
   (ignoring)
   pipes-core-0.1.0: dependency
   "void-0.5.6-2a27beac32f0c526d6cb6dc79bccfbd9" doesn't exist (ignoring)
   6.

What I don't understand, are the hashes. Where are they from and how to
solve theese dependency problems?
