Problems Deploying a rails app to Heroku - ruby-on-rails-3

Question

I am having problems deploying a Rails app to Heroku, I can't even run the Heroku console! (see below for the response I get from terminal)
I'm pretty new to rails and programming in general, so I don't really understand what the problem is here, would really appreciate some assistance!

Here is config/environments./production.rb, I commented out line 3 as I thought that might be the issue, but I get the same problem whether it's commented, uncommented or deleted completely!
Pingpong::Application.configure do
# /opt/local/bin/convert
# Settings specified here will take precedence over those in config/application.rb
# The production environment is meant for finished, "live" apps.
# Code is not reloaded between requests
config.cache_classes = true
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
# Specifies the header that your server uses for sending files
config.action_dispatch.x_sendfile_header = "X-Sendfile"
# For nginx:
# config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect'
# If you have no front-end server that supports something like X-Sendfile,
# just comment this out and Rails will serve the files
# See everything in the log (default is :info)
# config.log_level = :debug
# Use a different logger for distributed setups
# config.logger = SyslogLogger.new
# Use a different cache store in production
# config.cache_store = :mem_cache_store
# Disable Rails's static asset server
# In production, Apache or nginx will already do this
config.serve_static_assets = false
# Enable serving of images, stylesheets, and javascripts from an asset server
# config.action_controller.asset_host = "http://assets.example.com"
# Disable delivery errors, bad email addresses will be ignored
# config.action_mailer.raise_delivery_errors = false
# Enable threaded mode
# config.threadsafe!
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation can not be found)
config.i18n.fallbacks = true
# Send deprecation notices to registered listeners
config.active_support.deprecation = :notify
end
/app/config/environment
# Load the rails application
require File.expand_path('../application', __FILE__)
# Initialize the rails application
Pingpong::Application.initialize!

The problem is line 3. Make sure you have committed your changes and then push them to Heroku.
