Hi,

I just noticed that the upgrade of devel/py-urwid port to version 2.x (from 1.x) breaks several python packages.

Examples:

```
% khal interactive
Traceback (most recent call last):
  File "/usr/local/bin/khal", line 33, in <module>
    sys.exit(load_entry_point('khal==0.11.2', 'console_scripts', 'khal')())
  File "/usr/local/lib/python3.9/site-packages/click/core.py", line 1130, in __call__
    return self.main(*args, **kwargs)
  File "/usr/local/lib/python3.9/site-packages/click/core.py", line 1055, in main
    rv = self.invoke(ctx)
  File "/usr/local/lib/python3.9/site-packages/click/core.py", line 1657, in invoke
    return _process_result(sub_ctx.command.invoke(sub_ctx))
  File "/usr/local/lib/python3.9/site-packages/click/core.py", line 1404, in invoke
    return ctx.invoke(self.callback, **ctx.params)
  File "/usr/local/lib/python3.9/site-packages/click/core.py", line 760, in invoke
    return __callback(*args, **kwargs)
  File "/usr/local/lib/python3.9/site-packages/click/decorators.py", line 26, in new_func
    return f(get_current_context(), *args, **kwargs)
  File "/usr/local/lib/python3.9/site-packages/khal/cli.py", line 486, in interactive
    controllers.interactive(
  File "/usr/local/lib/python3.9/site-packages/khal/controllers.py", line 589, in interactive
    from . import ui
  File "/usr/local/lib/python3.9/site-packages/khal/ui/__init__.py", line 29, in <module>
    import urwid
  File "/usr/local/lib/python3.9/site-packages/urwid/__init__.py", line 72, in <module>
    from urwid.version import __version__, __version_tuple__
ImportError: cannot import name '__version__' from 'urwid.version' (/usr/local/lib/python3.9/site-packages/urwid/version.py)
```

```
% toot tui
Traceback (most recent call last):
  File "/usr/local/bin/toot", line 33, in <module>
    sys.exit(load_entry_point('toot==0.28.0', 'console_scripts', 'toot')())
  File "/usr/local/lib/python3.9/site-packages/toot/console.py", line 560, in main
    run_command(app, user, command_name, args)
  File "/usr/local/lib/python3.9/site-packages/toot/console.py", line 542, in run_command
    return fn(app, user, parsed_args)
  File "/usr/local/lib/python3.9/site-packages/toot/commands.py", line 346, in tui
    from .tui.app import TUI
  File "/usr/local/lib/python3.9/site-packages/toot/tui/__init__.py", line 1, in <module>
    from urwid.command_map import command_map
  File "/usr/local/lib/python3.9/site-packages/urwid/__init__.py", line 72, in <module>
    from urwid.version import __version__, __version_tuple__
ImportError: cannot import name '__version__' from 'urwid.version' (/usr/local/lib/python3.9/site-packages/urwid/version.py)
```

So far this seems to affect only python applications that are using a TUI interface. Tested on 13.2 with latest patches and upgrades.

Would it be sufficient to provide a patch creating a py-urwid1 port or would this mess things up even further?

Kind regards,

Jens
