This installs a patched ruby 1.9.3-p385 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.
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.
In your Gemfile add:
group :development, :test do
gem 'micro_migrations', :git => 'git@gist.github.com:33e9f92c229eb808a4fa.git'
end
You might want to add something like this to the Rakefile of apps that use a gem that uses micro_migrations:
ENV['SCHEMA'] = "#{Gem.loaded_specs['your-gem-name'].full_gem_path}/db/schema.rb"
