ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

Patched ruby 1.9.3-p125 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84).

Huge thanks to funny-falcon for the performance patches.

Whitelist Config

I'm a fan of MiniTest::Spec. It strikes a nice balance between the simplicity of TestUnit and the readable syntax of RSpec. When I first switched from RSpec to MiniTest::Spec, one thing I was worried I would miss was the ability to add matchers. (A note in terminology: "matchers" in MiniTest::Spec refer to something completely different than "matchers" in RSpec. I won't get into it, but from now on, let's use the proper term: "expectations").

Understanding MiniTest::Expectations

Let's take a look in the code (I'm specifically referring to the gem, not the standard library that's built into Ruby 1.9):

# minitest/spec.rb

module MiniTest::Expectations

	require 'haml'

	class ErbEngine < Haml::Engine
	def push_script(text, preserve_script, in_tag = false, preserve_tag = false,
	escape_html = false, nuke_inner_whitespace = false)
	push_text "<%= #{text.strip} %>"
	end

	def push_silent(text, can_suppress = false)
	push_text "<% #{text.strip} %>"

	#!/bin/sh
	export PATH=/bin:/usr/bin:/sbin:/usr/sbin

	usage=$(
	cat <<EOF
	$0 [OPTIONS] start/stop
	-s set speed default 256Kbit/s
	-p set port default 3000
	-d set delay default 350ms

	# Install rbenv
	git clone git://github.com/sstephenson/rbenv.git /opt/rbenv

	# Add rbenv to the path:

	Please note, these instructions are for OS X Lion.

	First, you need to get the IP address of your machine on your local network. In OS X, the easiest place to find this is in System Preferences > Network. If you're using DHCP on your local network, you will want to make sure your computer requests the same IP address when it renews it's IP address lease. I recommend configuring the DCHP Reservation settings on your router to accomplish this. Otherwise, you can specify a manual address in your network settings:

	1. Go to System Preferences > Network

	1. Click Advanced...
