 Yes, basically that is it. Then reboot, and cross your fingers. You should
 be able to back out of the changes using Firewire Disk mode, or a recovery
 boot with the Terminal, if disaster ensued.

 I have a 10.7 system that is running this now. It works. It crashed once
 -- I could not determine if the new libc++ was related to that crash.

 10.6 and earlier. Is the plan to eventually have that variant do the
 replacement for all MacOS releases?

 Probably not. 10.6 has no libc++.dylib, so that was low-hanging fruit.

 For newer systems, the only fix that MacPorts would likely support is the
 parallel installation of a newer libc++ (and related parts) from llvm-9 or
 llvm-10 say, and then as above, force it to be used instead of the system
 libc++ via some trickery.
