Git Push Heroku Master - Failing?

Question

so i tried pushing this app to heroku:

https://github.com/harrystech/prelaunchr    

i am using virtualbox with ubuntu.

i installed ruby using this:

$ sudo apt-get install curl   # Required
$ curl -L get.rvm.io | bash -s stable   # Get RVM
$ source ~/.bashrc   # Reboot the shell
$ rvm requirements   # To get the command below
$ sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-   core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion  # Install Libraries
$ rvm install 1.9.3   # Install ruby v1.9.3
$ rvm use 1.9.3
$ gem install rails   # Install rails (I had to run this command twice. Error trying to find railties the first time.. weird)    

However when i create my heroku app and tries to push the app to it it gives me this error:

for database i installed postgresql (dont know if it has any relevance though)

Assuming that git push heroku does indeed push to heroku (git remote -v would confirm it), the error messages are:

   Running: rake assets:precompile
   DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb.
   rake aborted!

You can find a few suggestion in " Ruby on Rails Rake assets:precompile error " and in this issue :

Open up config/environments/production.rb and make sure the following option is set to true:

# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true
config.serve_static_assets = true

Then run:

rake assets:precompile --trace RAILS_ENV=production
