[Nix-dev] [Hackage] How to install Hackage package, not presented in nixpkgs, locally?

[Andres Loeh]

Thanks, haven't tried it yet, but ...

> 7. nixpkgs$ ghc-pkg check

... the output of "ghc-pkg check" for the wrapped GHC is possibly a
bit suspicious. Have you tried

$ ghci -package pipes-core

$ ghci -package categories

Do these work or not?

Cheers,
  Andres
