Comment (by chrisscooke):

 OK, I have it figured out.  The xcode-select --install command does not
 work.  I don't know why.  In order to install the command line tools I had
 to get it from the developer's site.  From the Xcode menu in Xcode, I
 chose "Open Developer Tool" and then "More Developer Tools...".  This took
 me to a downloads page on the developer site, where I needed to login, and
 then I was able to find command line tools for Xcode 8.3.2.  (the url was:
 https://developer.apple.com/download/more/?=for%20Xcode).  After running
 this installer, Macports ran fine.
