 "man portfile" documents things that can be done in a portfile, not things
 that can be done in macports.conf. The caveat I mentioned above applies to
 the global option, not to the portfile option; the portfile option is
 supported and works as intended.

 and/or the man pages for port / portfile / macports.conf to mention this
 as a way to help others out in the future? At the moment I see:

 That part of the documentation is out of date. The portfile option was
 briefly called "configure.macosx_deployment_target" before being changed
 to just "macosx_deployment_target" several years ago. This section
 documents (or fails to document) the portfile option, not the global
 option.

 section of the documentation, or in that for each of the variables which
 can cause problems of this type when non-default.

 In fact the documentation barely mentions that we have pre-compiled
 binaries at all, and could really use some work.
