Comment (by cjones051073):

 This is an issue with cctools.

 The problem is cctools was recently updated to make a new Xcode variant
 the default on macOS systems that use Xcode 9 or newer, to fix issues with
 the fact the port at the moment provides a tool kit based on Xcode 8,
 which in some situations was causing issues. The new Xcode variant instead
 just installs wrapper scripts.

 The issue is MacPorts maintains previous variants, and as cctools had a
 different variant enabled by default before this is maintained.

 The work around is to force uninstall cctools, then reinstall it with the
 defaults.

 {{{
 sudo port -f uninstall cctools
 sudo port install cctools
 }}}

 After this, check your cctools installation is using the Xcode variant.

 This is not the first time I have seen this issue in the last few days. I
 we need to look into a way of forcing the use of the Xcode variant.
