 Replying to [comment:2 MSoegtropIMC]:
 > so this is more a general precaution than based on observations with the
 specific compiler and OS versions mentioned in
 /opt/local/libexec/macports/lib/port1.0/portutil.tcl ?

 Every case where the "ok" version is higher than "min" was added because
 of specific serious bugs that affected port builds.

 > Looking at the MacPorts code, I don't think setting
 configure.sdk_version or macosx_deployment_target in all ports I use would
 prevent the error.

 No, that would be in addition to the local modifications you made to base.
 BTW, if you really want to lie to MacPorts about what version of Xcode you
 have installed (hopefully understanding and accepting the consequences),
 you can override xcodeversion in macports.conf. Please just don't report
 any bugs after doing so.

 To allow you to use an older toolchain locally, you could most likely just
 install older Command Line Tools, as that is what most ports use anyway.
 You can also install multiple versions of Xcode at the same time and
 switch between them with xcode-select.

 Requiring users (and buildbots) to install an older version of Xcode when
 building certain ports is not going to be a workable general solution.
