Install linecache via bundler on heroku

I am using Ruby 1.9.2 using RVM on a rails 3.0 application.

which ruby
/home/ved/.rvm/rubies/ruby-1.9.2-p136/bin/ruby

when I push to heroku, I get the following error:

Not sure why this is failing and why 1.8 gems from ruby 1.8.7 is being used for this ?

Updated:

I tried recreating the app with 1.9.2 stack on heroku as follows:

heroku create test-sushi-app --stack bamboo-mri-1.9.2

now I am getting the following error:

Thanks @matt and @brandon for your help. This is how I could fix it.

1. via @matt - recreated the app with 1.9.2 using :

   heroku create test-sushi-app --stack bamboo-mri-1.9.2

2. Set the following environment variable :

   heroku config:add BUNDLE_WITHOUT="development:test" As discussed in - http://wesgibbs.me/post/1506018375/heroku-bundle-without-config-variable-wants-colons

3. Modified Gemfile to include ruby-debug19 conditionally :

   group :development, :test do if RUBY_VERSION =~ /1.9/ gem 'ruby-debug19' else gem 'ruby-debug' end end

Yeah, I have also faced with the same sorts of problem..I have only modified the below syntax in the gem file and it worked it out. Thanks a lot all of you.

   group :development, :test do 
       if RUBY_VERSION =~ /1.9/ 
         gem 'ruby-debug19' 
       else 
         gem 'ruby-debug' 
       end 
   end
