Comment (by nejucomo):

 I see that Tahoe-LAFS specifies `Twisted >= 11.0.0` (see
 https://github.com/tahoe-lafs/tahoe-
 lafs/blob/master/src/allmydata/_auto_deps.py#L32).

 Why doesn't the `./setup.py test` process see the latest version of
 twisted (say `14.something`) and decide that meets the constraint `>=
 11.0.0` and install *that*?
