Try fixing the <exe> section in your <launcher> config. 
I use '<exe>./zone</exe>' 
 
In my launcher table I have a single row, name=zone dynamics=5 
When I launch it boots 5 dynamic zones. 
 
I'm not honestly sure how the dynamic zones work though.  It either means I can keep any 5 zones up at a time or that the zone server maintains 5 listeners for the purpose of booting new zones as they are needed.
