 THANK YOU jeremyhu!

 Indeed that worked for me.  Installing the Beta Command Line Tools from
 disk image put the files at the root level.  As I mentioned in the my
 other posts, I started by installing Xcode Beta and installing the Beta
 Command Line Tools from within Xcode Beta.  That put the tools under Xcode
 rather than the disk root level.  And OS X SIP prevented me from just
 moving/copying the header file.

 By the way, your link would not work for my basic Apple Developer account.
 But I just logged in, went to Downloads and found the disk image myself.
