ええと，松本も全部は把握していないんです．

私の手元にあるrubyの実績のあるマシンというと

  * i486-linux-aout
  * SunOS 4.1.3
  * Solaris 2.4
  * AIX 4.1

くらいでしょうか．あと

  * i486-linux-ELF
  * i486-linux-freebsd
  * hppa-hpux
  * nextstep  

などでも動くと思われます．情報のある人は追加してください．

うーむ，もう忘れてしまった．^^;;;

こんな感じでどうでしょう．tktimer.rbの改造です．

# This script generates a counter with start and stop buttons.

require "tk"
$ticktext =  '0.00'
$label = TkLabel.new {
  textvariable :$ticktext
  relief 'raised'
  width 10
  pack('side'=>'bottom', 'fill'=>'both')
}

TkButton.new {
  text 'Start'
  command proc {
    if $stopped
      $stopped = FALSE
      tick
    end
  }
  pack('side'=>'left','fill'=>'both','expand'=>'yes')
}
TkButton.new {
  text 'Stop'
  command proc{
    $stopped = TRUE
  }
  pack('side'=>'right','fill'=>'both','expand'=>'yes')
}

$seconds=0
$hundredths=0
$stopped=TRUE

def tick
  if $stopped then return end
  Tk.after 50, proc{tick}
  $hundredths+=5
  if $hundredths >= 100
    $hundredths=0
    $seconds+=1
  end
  $ticktext = format("%d.%02d", $seconds, $hundredths)
end

root = Tk.root
root.bind "Control-c", proc{root.destroy}
root.bind "Control-q", proc{root.destroy}
Tk.root.focus
Tk.mainloop

ただし，tk.rbが思いきりバグってましたので，以下のパッチを当
てないと動きません．
