Comment (by ryandesign):

 Yes, drastic, because

 1. it is unrelated to the problem the user was experiencing, which was
 caused by not having the correct version of the command line tools
 installed; we should not introduce irrelevant information;
 2. the user must uninstall and reinstall all ports;
 3. the user must forever build all ports from source, until we make some
 changes to base to allow us to distribute these binaries, and then set up
 the buildbot to do that;
 4. although it may solve some problems, it will most likely eventually
 cause the user to encounter some build error that is unique to that
 configuration, which most developers do not test, and will thus take
 additional time for the developer to solve.

 I don't disagree that more and more software requires C++11, but I feel
 that before we wholesale recommend users use LibcxxOnOlderSystems, we need
 to improve the user experience of doing so.
