Bug report

Bug description:

When running tests through the iOS testbed,.pth files that are installed by packaged (such as the setuptools "distutils_hack") will not be processed.

This surfaced during testing of an iOS patch for Pillow, which uses pyroma; pyroma depends on distutils; but because the .pth file installed by setuptools isn't processed, distutils can't be imported, and so neither can pyroma.

CPython versions tested on:

3.13
