… compat pkg_resources is no longer bundled by default with Python 3.12+ (it requires setuptools to be installed explicitly). Use importlib.metadata.entry_points as the primary implementation and fall back to pkg_resources for older Python versions where importlib.metadata may not be available.
…staller pretty_version_text() is called as a default argument at module import time. It invokes iter_entry_points() and __import__() on storage broker packages, which fails in PyInstaller's isolated analysis subprocess where no entry points are registered. This causes PyInstaller to silently exclude dtool_cli.cli from the bundle. Defer the call using sys._MEIPASS check so it only runs when the CLI is actually invoked, not during bundled-app import.
