module_function
def foo

end
def bar
"I am bar"

Party.foo # => "I am foo"
Party.bar # => "I am bar"

The documentation is very straight forward and the mentioned example
also cleared all the lines except the one mentioned inside **.
http://ruby-doc.org/core-2.0.0/Module.html#method-i-module_function
Creates module functions for the named methods. These functions may be
called with the module as a receiver, and also become available as
instance methods to classes that mix in the module. Module functions are
copies of the original, and so may be changed independently. The
instance-method versions are made private. *If used with no arguments,
subsequently defined methods become module functions.*
module Mod
def one
"This is one"
end
module_function :one
end
class Cls
include Mod
def call_one
one
end
end
Mod.one #=> "This is one"
c = Cls.new
c.call_one #=> "This is one"
module Mod
def one
"This is the new one"
end
end
Mod.one #=> "This is one"
c.call_one #=> "This is the new one"
Please help me to understand what does mean by "If used with no
arguments, subsequently defined methods become module functions."?

Thanks! I think this is the right direction and I am gonna give it a
try. I just test adding ruby path to both /etc/launchd.conf and
/etc/paths. After rebooting, I thought it would work but not. Launchd
still does not recognize the correct ruby version. I will report once it
works.
