First of all, I think Postgres is the issue here. I believe Heroku and Rails builtin PG causes some issue. Try editing your gem page like this:

group :development, :test do
     gem 'sqlite3'
end

group :production do
     gem 'pg'
     gem 'rails_12factor'
end

Then, do "bundle install".

If this doesn't work try doing "bundle install --without production"

Hope this helps.
