I don't understand this idea. Some ports don't have variants and  
don't need any. Say, the readline port. It has no variants. It  
depends on no other packages. Its configure line features no --with- 
foo or --enable-foo flags. What meaningful variants would you suggest  
adding to this port, for example?
