If user's Ruby/Tk returns no error for "TkPackage.require('Tix')", 
he doesn't need to modify their Ruby. 
Extract needed classes from Tix.rb included tcltk-ext, 
and add them to your application. 

# Of course, need "TkPackage.require('Tix')" after "require 'tk'". :-)

If you want to use Balloon, use TixBalloon class. 
The class-tree of TixBalloon is

  TkWindow
    +-- TixInputOnly
          +-- TixPrimitive
                +--  TixShell
                      +-- TixBalloon

Therefore, add TixInputOnly, TixPrimitive, TixShell, and TixBalloon 
to your application. 
Then you can use Balloon widget in your application. 
  e.g.
         TkButton.new(nil, 'text'=>'hello',
                      'command'=>proc{print "hello\n"}) {|b|
           TixBalloon.new(nil, 'initwait'=>200, 'state'=>'balloon') {
             bind(b, 'balloonmsg'=>'Balloon Help')
           }
           pack('fill'=>'x')
         }
         Tk.mainloop
