Ой-ой-ой!

Другими словами, библиотека, которая сейчас находится в сизифе,
неработоспособна.  Но после пересборки она "автоматически" становится
работоспособной, причем без изменения зависимостей.  Вот она вся
бинарная совместимость.  Т.е. нет никакой бинарной совместимости. :(

Радует в некотром смысле только одно: робот работает правильно.

То же самое.

А это вообще странно.  Кажется этот пакет просто забыли удалить из
репозитария:
