Fix for one command only

nix-build flake:nixpkgs -A hello
nix-build -I nixpkgs=flake:github:NixOS/nixpkgs/nixos-23.05 '<nixpkgs>' -A hello
NIX_PATH=nixpkgs=flake:nixpkgs nix-build '<nixpkgs>' -A hello

Fix it decleratively

makeWrapper and wrapProgram

Nix generally assumes run-time dependencies is a subset of the build-time dependencies.

This means many Nix builder functions try to automatically scan the output for runtime dependencies and "rewrite" them for runtime usage.

However shell scripts which are often exported by packages do not get this automatic scanning treatment.

This means you have to use the makeWrapper package and use either the makeWrapper or wrapProgram utility functions.
