Deploy a simple test app with Sinatra + DataMapper + Postgres + Heroku returns: Installing do_sqlite3 (0.10.7) error - postgresql

Question

Goal: Deploy a simple test app with Sinatra + DataMapper + Postgres + Heroku
Issue: When using gem 'dm-postgres-adapter' gem 'dm-sqlite-adapter' to push the app to Heroku I get this.
Installing do_sqlite3 (0.10.7) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks!
I have visited that github link and someone had the same issue but gets directed to Heroku, https://github.com/carlhuda/bundler/issues/1488 . I have sent an email to the mailing list of Heroku and am waiting for a reply.
I ran into LoadError: no such file to load -- dm-sqlite-adapter
So I added that into the Gemfile and Gemfile.lock and this is as far as I can ever get
I have tried to instal and setup Postgres locally but thats brand new set of pains that i'm slowly learning but can not get to work yet.
I have also read each and every question here with a simular issue, some progressed me to this point and some dont have responses from the asker and leave it a mystery.

The error when installing do_sqlite (Installing do_sqlite3 (0.10.7) with native extensions...) is simply because this gem requires the sqlite3 libraries to be installed, and they are not on Heroku. To fix it, remove dm-sqlite-adapter (which is what idepends on do_sqlite) from your Gemfile. If you want to keep Sqlite for development and use Postgres for production, you can use Gembundler's groups:
gem 'dm-postgres-adapter', :group => :production
gem 'dm-sqlite-adapter', :group => :development
This way, the postgresql adapter will be installed in production on Heroku, but sqlite will be used locally for development.
The line in your code that sets up Datamapper is:
DataMapper.setup(:default, ENV['DATABASE_URL'] || "sqlite3://#{Dir.pwd}/recall.db")
This looks for a environment variable DATABASE_URL and if it's present uses it otherwise uses the sqlite url. Getting the LoadError: no such file to load -- dm-sqlite-adapter error suggests that this variable isn't actually set. Run heroku config, there should be entries for DATABASE_URL and SHARED_DATABASE_URL. If they are not set you need to add the database.
Have a look at this other SO question which deals with a similar issue. The solution there was to run heroku addons:add shared-database:5mb.
