nix you need to eval dollar_configurePhase

• when using nix dev, you shouldn’t just run the configurePhase, but instead use eval $configurePhase or runHook configurePhase
• this is how the generiBuilder does it
• normally this does not make a difference, but when a setup-hook sets a variable named configurePhase, which should be used, when running directly the old function will bu run and not the one by the setup-hook
  • see: configurePhase is not same as eval dollar_configurePhase
