I can build the container without any packages successfully.

Running `nix-env --install age` directly results in the error.
Running `nix-env -iA nixpkgs.age` directly installs successfully.

Using the `useAttributePath` option with package `age` is successful.
Using the `useAttributePath` option with package `nixpkgs.age` is successful.

I'm relatively new to nix so maybe there's something obvious I'm missing, but if the current error with `nix-env --install` is expected, it might be more intuitive to have `useAttributePath` on by default?
