slack_botkit not defined in middleware

Using Botkit 0.2.2 on Mac OSX el Capitan

My server throws a ReferenceError when trying to do custom slash commands.

The error points to slack_authentication.js where there is no reference made to slack_botkit

slack_botkit.log(
            '** Requiring token authentication for webhook endpoints for Slash commands ' +
            'and outgoing webhooks; configured ' + tokens.length + ' tokens'
        );

+1 on outgoing webhooks.

var controller = Botkit.slackbot(config);
var bot = controller.spawn({
  incoming_webhook: {
    url: process.env.INCOMING_WEBHOOK_URL
  }
});

controller.setupWebserver(process.env.PORT, function(err, express_webserver) {
  controller.createWebhookEndpoints(express_webserver,
      [process.env.OUTGOING_WEBHOOK_TOKEN]);
});

At this point, it gives the same ReferenceError:

Downgrading to 0.2.1 seems to fix the issue.

BTW downgrading to 0.2.1 will break the token check when the slash command POST comes in to your server.
