powerdns meta packages?

[Joe Holden]

Hi guys,

What is the process for adding/submitting "meta" packages for ports for 
example powerdns that have multiple backend options and the default 
isn't suitable, or failing that have the ability to install powerdns 
with default backend but allow the installation of others?

Currently the port defaults to postgres, in this case I'd like sqlite 
backend for some servers (slaves), at the moment I'm just building that 
manually but it does mean I can't just do 'pkg upgrade'

Cheers,
J
