What about arranging it like this:

  class Tool_Generic
    #methods to handle generic stuff common to PC and UNIX
  end

  class Tool_PC < Tool_Generic
    #methods do PC specific stuff
  end
     
  class Tool_UNIX < Tool_Generic
    #methods do UNIX related stuff
  end

  if $PLATFORM == "PC"
    class Tool < Tool_PC
    end
  else
    class Tool < Tool_UNIX
    end
  end

then you could just use class Tool.

(the syntax would be completely wrong as I haven't played around with
building up classes out of other classes. Any corrections welcome as
I would be interested in seeing how to do this).
