 Running on 10.15 (24A335), I installed the latest RC 16 Xcode from Apple
 and then reinstalled MacPorts (2.10.1, from source).  When I try to
 install cmake-bootstrap (among a few others as this is a dependency), I
 receive the following:
 {{{
 :info:configure CMake 3.9.6, Copyright 2000-2017 Kitware, Inc. and
 Contributors
 :info:configure C compiler on this system is: /usr/bin/clang -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk -arch
 x86_64 -std=gnu11
 :info:configure ---------------------------------------------
 :info:configure Error when bootstrapping CMake:
