Problem after deploying on heroku with okland:accounts-phone package

Hello,

I used the package okland:accounts-phone in my development machine and everything worked fine.
But when i deployed it to heroku, the deployment process was successful but the app shows and error.

On checking the logs, i get the error as

I checked the file accounts-phone.js to find out that the global variable Package is not defined

(function () {
/* Imports */

**var Meteor = Package.meteor.Meteor;**
var global = Package.meteor.global;
var meteorEnv = Package.meteor.meteorEnv;
var NpmModuleBcrypt = Package['npm-bcrypt'].NpmModuleBcrypt;
var Accounts = Package['accounts-base'].Accounts;

help me with this issue as i have to deploy the app as per the deadline.
Thanks in advance
