this._computeClient = require('pkgcloud').createClient('compute',{
  enableExtensions: true,
  provider: this._stackProvider,
  username: this._stackUsername,
  apiKey: this._stackApiKey,
  authUrl: this._stackAuthUrl
});

this._storageClient = require('pkgcloud').createClient('storage',{
  enableExtensions: true,
  provider: this._stackProvider,
  username: this._stackUsername, 
  apiKey: this._stackApiKey,
  authUrl: this._stackAuthUrl
});

this._dnsClient = require('pkgcloud').createClient('dns',{
  enableExtensions: true,
  provider: this._stackProvider,
  username: this._stackUsername,
  apiKey: this._stackApiKey,
  authUrl: this._stackAuthUrl
});

// Or with a callback ( better )

this._computeClient = null;
var _this = this;

require('pkgcloud').createClient('compute',{
  enableExtensions: true,
  provider: this._stackProvider,
  username: this._stackUsername,
  apiKey: this._stackApiKey,
  authUrl: this._stackAuthUrl
}, function (err, client) {
  _this._computeClient = client;
});

why not just have service be an option?

for example:

var client = pkgcloud.createClient({
  service: 'compute',
  provider: 'rackspace',
  ...
});
