Cannot find module twilio when using heroku and meteor - heroku

Question

I cannot figure out how to get the twilio npm module working on a heroku dyno using meteor js. It works great on localhost, but it crashes on heroku. This is how I built my heroku app:
heroku create meteorherokutwilio --stack cedar --buildpack https://github.com/oortcloud/heroku-buildpack-meteorite.git
heroku config:add ROOT_URL=http://meteorherokutwilio.herokuapp.com/
heroku labs:enable websockets -a meteorherokutwilio
git push heroku master
I've added twilio to my meteor project like this:
mrt add twilio
This is how I'm loading twilio:
var client = Npm.require('twilio')("key", "secret");
This is the error:
/app/.meteor/heroku_build/app/programs/server/boot.js:186
}).run();
^

I've also made a git repo with the minimum amount of code to demonstrate the problem: https://github.com/esromneb/meteor-heroku-twilio/

Npm.require works only for standard node packages (well, it works for packages it found installed, but you should only rely on it for standard packages, unless you want to manually add packages to your Heroku server and each server you'd like to run in the future).
For all other npm packages, there's npm meteorite package.
Add it to your project with mrt add npm command.
Then create packages.json file with a list of all required packages, for example:
{
"twilio": "1.5.0",
"oauth": "0.9.11"
}
Afterwards, include your package with Meteor.require:
var client = Meteor.require('twilio')("key", "secret");
