What's happening is probably that you have RUBYOPT=-rubygems

which is a shortcut way to require rubygems, sometimes setup by the one 
click installer.  So when you ruby ruby -r debug some_file

it ends up running a require BEFORE it runs that file, and, 
conveniently, brings you to a debug prompt in the pre-file file.

To get around it:
gem install ruby-debug
then within debugtest.rb
require 'ruby-debug'
debugger
Cheers!
-r
