 I was going to install the perftools.rb to research a CPU performance.

 {{{
 $ sudo macgem install ruby_core_source

 # I do a fork of an original project because 'require "rubygems"' was
 necessary.

 $ git clone https://github.com/Watson1978/perftools.rb.git
 $ cd perftools.rb/
 $ macgem build perftools.rb.gemspec
 $ sudo macgem install perftools.rb-0.5.4.gem
