As was cautioned in the pull request that added the "portend" dependency
4 years ago, this is the reason why it's dangerous to rely on relatively
minor third-party packages.  CherryPy now depends on portend, which
depends on tempora, which depends on jaraco.  The "save_method_args"
option was added to jaraco two weeks ago.  Your jaraco version is now
too old.
