After reading wiki:CompilerSelection, it's still unclear what action to take as a user. Is that something I can do as a command line parameter or environment variable passed to port install …? All the applicable instructions seem to recommend Portfile modifications.

That warning is of use for Portfile developers, and is obviously just confusing for users. Apologies for that.

The issue seems to be:

Yeah. We need a ​developer mode.
