      This simple Node app:

      'use strict'
      
      var mongodb = require('mongodb')
      
      var server = new mongodb.Server('localhost', 6379)
      var db = new mongodb.Db('integration', server)
      
      db.dropCollection('testCollection2', function() {})
      

      results in this error when executed:

      $ node test/versioned/mongodb/test.js
      /Users/nwolfe/work/nr/nodejs_agent/test/versioned/mongodb/node_modules/mongodb/lib/db.js:489
        if (self.s.topology.capabilities().commandsTakeWriteConcern) {
                                          ^

      Is this little app incorrect, or is this a bug in the driver?
