Comment (by kencu):

 Right. I guess we could do one of these:

 1. duplicate the logic of the cxx11 1.1 PG in the Portfile (too inelegant)
 1. call the `cxx11.add_dependencies` function directly prior to setting
 the build.env
 1. change the cxx11 1.1 PG to set the flags when the portgroup is parsed
 (move the flag setting out of the callback proc(). Or just do it twice,
 once when parsed, and leave it in the callback proc(). No harm doing that,
 I think.

 Option 3 would fix it for all ports, I think. Don't see any downside to it
 at this moment.
