Hi Richard,
run "nix-env -e haskell-hiberico-ghc7.8.3-1-shared" to remove the old
version of the package from your profile. Once you've done that, you can
install the new expression from "haskell-ng" into your profile without a
collision.
Best regards,
Peter

So I'm having an issue with converting a package to the new
haskellngPackages. When I try and install it, I get a collision error
