I have another 'tar' ahead of Apple's in my path that does not have the Apple-specific flag features. if I remove the addition of '--no-mac-metadata' (added to resolve #109980) it passes. Or if I hardcode the test to use Apple's at line 1740:
- tar_cmd = ['tar', '-cf', 'archive2.tar', base_dir]
+ tar_cmd = ['/usr/bin/tar', '-cf', 'archive2.tar', base_dir]
it passes. But interestingly, if I hardcode to use Apple's and remove that flag, it still passes.
