How about:

  if $DEBUG
     require 'debug'
  else
     require 'no_debug'
  end

and in file "debug.rb" you would define you debug method(s), making them as
heavy as you pleae, and in file "no_debug.rb" you would just define empty
methods like: 

   def debug; end


Alternatively:

Comment out your debug code like this for exaple:

   #DEBUG debug( var1, var2, var3 )

and then you can generate the debugging version of your source by:

   ruby -pe "$_.gsub( /(^\s+)#DEBUG/, '\1' ) <source.rb > debug.rb
