Right. That is my point. You need to make sure when you package the  
thing up for redistribution that you do not violate any copyright  
terms of the individual components. If you cannot ensure that for some  
components, an alternative is that the user takes down those  
components by themselves. There is no need that all components of a  
package have same copyright license.
