New description:

 Upgraded two computers to Sierra.
 Upgraded both to macports 2.3.4.
 Xcode 8.0 installed on both.

 Trying to install mercurial (version 3.9.1).
 One computer installs without problems.
 Other fails with following error:

 Tried multiple rebuilds and cleaning the partial builds.
 Any thoughts appreciated.

Comment:

 Errors encountered in system headers usually mean you haven't installed
 the latest version of the Xcode command line tools. Use can use `xcode-
 select --install` to do that.
