Does pkg_add download all missing dependencies at once before  
installing all missing packages? If not: there should be no change in  
behavior in pkg_add if we wswitch to explicit dependencies.

Not every port contains an explicit dependency, if it is already  
satisfied by an implicit dependency. Therefore I assume you may miss  
to update a port in portmanager.

Aside from this, portupgrade uses the dependency information regorded  
in /var/db/pkg (or INDEX-X, I'm not sure), which is written by the  
infrastructure of the Ports Collection. I assume the upgrade shell  
script we got recently in ports (sorry, I can't remember the name)  
also uses the information provided by the ports collection, so it  
would benefit too from switching to explicit dependencies.

Bye,
Alexander.
