"Failed to install gems via Bundler" when deploying to Heroku

Background: I'm working through the book "Ruby on Rails 3 Tutorial" by Michael Hartl. I've gotten to the point where I'm setting up heroku. The text directs me to use sqlite3, but it seems that heroku no longer allows a sqlite3 backend. So, I'm trying to use postgres instead.

I'm working on a Mac, OS 10.6.8.

Problem: I try to do 

$ git push heroku master

Then I get

Counting objects: 69, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (55/55), done.
Writing objects: 100% (69/69), 26.69 KiB, done.

       Running: bundle install --without development:test --path vendor/bundle --    binstubs bin/ --deployment
       You are trying to install in deployment mode after changing
       your Gemfile. Run `bundle install` elsewhere and add the
       updated Gemfile.lock to version control.
       You have added to the Gemfile:
       * pg
       You have deleted from the Gemfile:
       * sqlite3
 !
 !     Failed to install gems via Bundler.
 !
 !     Heroku push rejected, failed to compile Ruby/rails app

With respect to "Run 'bundle install' elsewhere" -- what does elsewhere mean in this case? In another directory? I've tried that, to no avail. Also there's no Gemfile.lock file to add. In summary: I'm confused.

You need to let the gem installer know where your PostgreSQL installation is located, because it needs to use some of those files when installing.

Hmm, that seems to indicate that you've modified your Gemfile to include the pg gem, but haven't run bundle install (on your dev machine) to lock those gems down. Running bundle install will resolve all gem dependencies and generate a new Gemfile.lock. That's the file you should check into git and then attempt the deploy.

Run the following on your development machine:

bundle install
git add Gemfile.lock
git commit -m "Locking gems"
git push heroku # assumes default remote named heroku
