Installing rails (per the Rails book, 3rd edition):

$ sudo apt-get update
$ sudo apt-get install build-essential
$ sudo apt-get install rubygems ruby1.8-dev libsqlite3-dev
$ sudo gem install -y rails

I got this error:

ERROR:  While executing gem ... (Gem::GemNotFoundException)

Per the Army of Evil Robots article, I did the following:
