II. Creating a Certificate Signing Request (CSR)
 
Note: To create an SSL certificate, you must first generate and submit a Certificate Signing Request (CSR) to the Certification Authority (CA) (i.e. GoDaddy). The CSR contains your certificate-application information, including your public key. The CSR will also create your public/private key pair used for encrypting and decrypting secure transactions.
 
These instructions are based on my experience using a Mac OS X laptop.  The following probably won't work if you are not working from a unix-based system (i.e. Mac OS X / Ubuntu Linux / etc.).
 
Steps to create a CSR:
 
1. Make a new directory to hold your project's SSL-related stuff.  It doesn't really matter where you put this, but I recommend not putting it in your rails project (i.e. alongside app, config, db, etc.), as it will get included in your git repository if you do.  Rather, I put it in a folder that is one level above my rails project.

Installing older Rubies (e.g. Ruby 1.8.7) on a clean install of Lion and Xcode

The latest Xcode and Command Line Tools for Xcode changes the default compiler from gcc to the llvm compiler. Only ruby-1.9.3-p125+ is LLVM ready. So, you will have to install gcc-4.2 to compile older versions of Ruby. More detail here https://github.com/mxcl/homebrew/wiki/Custom-GCC-and-cross-compilers.

This worked for me. I hope it saves some people time:

brew install https://raw.github.com/adamv/homebrew-alt/master/duplicates/apple-gcc42.rb
CC=/usr/local/bin/gcc-4.2 rvm install 1.8.7
