Since what you're attempting won't work, as Enda described, here's another 
idea - which may or may not work for your situation.

1) create a zone on a system
2) add the package to it
3) clone the zone
4) detach the clone
5) copy the detached zone to any system which needs the package and zone
6) attach the zone to those systems
