`devbox add gcc` fails on MacOS 15.7.1

Reproduce with devbox init and devbox add gcc on Apple Silicon macOS, then inspect the Nix build invocation in internal/nix/build.go and the package handling mentioned in the logs. Determine whether the failure is in Devbox or the Nix package build; done means gcc installs successfully on the reported system.

What happened?

I cannot install gcc using devbox on my MacOS 15.7.1 (Apple M4 Pro)

Steps to reproduce

1. devbox init
2. devbox add gcc

Command

add

devbox.json

{
    "$schema": "https://raw.githubusercontent.com/jetify-com/devbox/0.14.2/.schema/devbox.schema.json",
    "packages": [],
    "shell": {
      "init_hook": [
        "echo 'Welcome to devbox!' > /dev/null"
      ],
      "scripts": {
        "test": [
          "echo \"Error: no test specified\" && exit 1"
        ]
      }
    }
  }

Devbox version

0.16.0
