http://young-robot-995.heroku.com deployed to Heroku
but I am getting this error
In my local development it looks like i am using ruby 1.8 but on heroku it looks like its 1.9.1 maybe thats causing it....any ideas on how to fix this
here is my gemfile if that will help
source 'http://rubygems.org'
#gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
gem 'rails', '2.3.8'
gem 'will_paginate', '2.3.12'
gem 'googlecharts'
gem 'faker'
gem 'httparty'
gem 'bandsintown'
gem 'itunes-search-api','0.1.0', :path => 'vendor/gems/itunes-search-api-0.1.0'
gem 'i18n', '0.4.2'
gem "giggly", "~> 0.1.2"
gem "ruby-paypal",'0.0.5', :path => 'vendor/gems/ruby-paypal-0.0.5'
group :development, :test do
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
end

Looks like you need to modify your Gemfile, try using the one below and see if that works for you:
source 'http://rubygems.org'
gem 'rails', '2.3.8'
gem 'will_paginate', '2.3.12'
gem 'googlecharts'
gem 'faker'
gem 'httparty'
gem 'bandsintown'
gem 'itunes-search-api','0.1.0', :path => 'vendor/gems/itunes-search-api-0.1.0'
gem 'i18n', '0.4.2'
gem "giggly", "~> 0.1.2"
gem "ruby-paypal",'0.0.5', :path => 'vendor/gems/ruby-paypal-0.0.5'
group :production do
gem 'test-unit'
gem 'pg'
end
group :development, :test do
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
end
