            # end

            # Bundle gems for the local environment. Make sure to
            # put test-only gems in this group so their generators
            # and rake tasks are available in development mode:
            # group :development, :test do
            #   gem 'webrat'
            #end

Your bundle is complete! Use bundle show [gemname] to see where a bundled gem is installed.

HOw can i resolve this conflict???

It looks like you might have Bundler set to specifically require 1.0, and Heroku's wanting to use 1.1. There would be a line in your Gemfile that reads gem bundler, "~> 1.0" or something similar - just knock off the comma and everything after so that it just reads gem bundler.

If that's not the case, can you post your Gemfile?
