I am starting chapter 13 or Programming Ruby trying to debug the
following factorial program (in file t.rb) on page 163:

def fact(n)
  if n <= 0
    1
  else
    n * fact(n -1)
  end
end

p fact(5)

When I run the command:
ruby -r debug t.rb
Instead of the debugger loading t.rb program, it loads something else
and displays the following output:

C:\RubyPrograms\PickAxeBook>ruby -r debug t.rb
Debug.rb
Emacs support available.

c:/ruby/lib/ruby/site_ruby/1.8/ubygems.rb:10:require 'rubygems'

I am not sure what is happening here.  Please note that I am on Windows
XP machine.  When I try to list by typing list 1-9, the following output
is displayed.  I may have messed up the ruby path loader since I was
messing with it.  Why did it persist across the sessions though?

(rdb:1) list 1-9
[1, 9] in c:/ruby/lib/ruby/site_ruby/1.8/ubygems.rb
   1  # This file allows for the running of rubygems with a nice
   2  # command line look-and-feel: ruby -rubygems foo.rb

This totally perplexes me.  Help!!!

This is getting stranger!  I rebooted in Fedora Core 5 Linux (I have a
dual boot machine).  Copied the same program from Windows partition and
ran it in Linux.  Works perfect!

Any clues on how to troubleshoot on Windows side?
Thanks in advance.
