 Replying to [comment:2 barracuda156]:
 > Just add to the portfile and let it do the magic?

 Yes, except of course you'll need to add the directives that tell it to
 add specific things for specific architectures. Unfortunately
 [ticket:32428 the muniversal portgroups are not documented well] so you
 may need to look at other ports that use them to find out how to do that.

 > Does it matter which one is used, 1.0 or 1.1?

 Presumably 1.1 was created to address some deficiency of 1.0 so presumably
 1.1 is the one to go for. But 1.0 and 1.1 are pretty different in their
 interface, so as you go looking at other ports for examples, you'll need
 to find examples that use the version of the portgroup you want to use.
