script to make sure you have rcodetools installed for all rvm rubies

install_rcodetools.rb

#!/usr/bin/env ruby

rubies = `rvm list`.split(/\s+/).find_all{|s| s.include? "ruby"}

def fetch_for(rvm_spec)
	system "rvm use #{rvm_spec}"
	system "gem install rcodetools"
end

def valid_gemset?(name)
	!(name.include?("(default)") or
		name.include?("global") or 
		name.empty?)
end

rubies.each do |rb|
	fetch_for rb
	gemsets = `rvm gemset list`.split(/\s+/).find_all{|s| valid_gemset?(s)}
	gemsets.each do |gemset|
		fetch_for "#{rb}@#{gemset}"
	end
end

has some bugs to work out...
