Comment (by nad@…):

 This is actually rather more serious than I originally thought.  The
 problem is that the upstream ports bundle into them a source file from the
 Python source distribution and the original, un-updated upstream version
 is now way out of date for all Python versions.  Taking a quick look at
 the existing MacPorts patches, the universal build stuff has changed a bit
 in the new version and I think it can still be safely removed; likewise
 for the 10.9.5 / Xcode 5 workaround which only applies to the Apple-
 supplied Pythons.  The patches for `readline_path.py` and `readline.pth`
 and the `extra_path` patch to `setup.py` are still needed, I think: they
 simulate what a setuptools install would do to alter `sys.path`.
 ticket:45301#comment:9 has some details on what you should expect to see
 if pyxx-readline is properly installed.  If you like, I would be willing
 to smoke test the port if you can make the updates available.
