vagrant ssh on stellar single-peer seems to fail (probably easy, but I am too jet-lagged to sort it out tonight)

Vagrant failed to initialize at a very early stage:

The directory Vagrant will use to store local environment-specific
state is not accessible. The directory specified as the local data
directory must be both readable and writable for the user that is
running Vagrant.

Local data directory: /Users/kevin/code/stellar-things/vagrant-examples/single-peer/.vagrant
