    In Fedora, we remove the bundled wheels; pip & co. are supplied (and kept updated) by the system. I believe this is good practice.

    However, removing any file from the CPython source checkout makes test_freeze fail:

    Traceback (most recent call last):

    It looks like this test is recreating uncommited modifications, is it OK to change it to support deletions as well?
    Also, git status --porcelain should be used to get the output in a stable format.
