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


	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.

	(($) ->
	class CheckboxSource
	constructor: (@root) ->
	data: -> _.map @root.find(":checkbox:checked"), (obj) -> $(obj).val()

	$ ->
	$("*[data-checkbox-source]").each ->
	self = $(this)
	source = new CheckboxSource(self)
	key = self.data("checkbox-source")

	# Ruby 1.9.3
	# IRB

	import redis
	import random
	import pylibmc
	import sys

	r = redis.Redis(host = 'localhost', port = 6389)
	mc = pylibmc.Client(['localhost:11222'])

	# Add all gems in the global gemset to the $LOAD_PATH so they can be used even
	# in places like 'rails console'.
	if defined?(::Bundler)
	global_gemset = ENV['GEM_PATH'].split(':').grep(/ruby.*@global/).first
	if global_gemset
	all_global_gem_paths = Dir.glob("#{global_gemset}/gems/*")
	all_global_gem_paths.each do \|p\|
	gem_path = "#{p}/lib"
	$LOAD_PATH << gem_path
	end
