New description:

 I just upgraded to Mac OSX 10.15 Sequoia with XCode 16. I have the command
 line tools installed. I deleted my old `/opt/local` and reinstalled
 MacPorts from scratch using the file `MacPorts-2.10.1-15-Sequoia.pkg`. The
 build fails when trying to install cmake-bootstrap. The build log for
 cmake-bootstrap is attached. I think the relevant lines are:
 {{{
 :info:configure Error when bootstrapping CMake:
 :info:configure Cannot find appropriate C++ compiler on this system.
 :info:configure Please specify one using environment variable CXX.
 :info:configure See cmake_bootstrap.log for compilers attempted.
 }}}

 The main.log file is attached.

Comment:

 This may be a duplicate of #70716 which is a duplicate of #70750. Please
 try the solution in ProblemHotlist#clts16. If that doesn't work, please
 attach the cmake_bootstrap.log file mentioned in your error message.
