Rails without alignment

I did some work with Ruby on Rails today; made less progress than I would have liked.

The problem I encountered was a mis-alignment of my installation of Ruby and the Agile Web Development with Rails book. I have Rails version 2 installed; my copy of the book is for version 1. I need a later edition of the book.

I made some progress, and have a pretty good idea of Rails and how it organizes Ruby code. I want to pursue this, and getting the later book should be possible.
