  Changed paths:
    M buildout.cfg

  Log Message:
  -----------
  Use older tox.

Seen on some other Zope packages as well.
Otherwise you may run into this error:

```

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):

    assert newdist is not None  # newloc above is missing our dist?!
AssertionError
```

And when you then run it a second time to see if that helps, the error changes because cruft is left behind:

```

  Installing interpreter.
