cmake-3.19.7 fails to build

[greytomorrow]

As per the summary. Attached is a copy of /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_cmake/cmake/main.log

Before creating this ticket I saw ​https://trac.macports.org/ticket/62178 but that deals with non-existing dependencies (python2.7). When I run port info cmake I get the following output...

cmake @3.19.7 (devel)
Sub-ports:            cmake-devel
Variants:             docs, python27, python35, python36, python37, python38,
                      python39, qt5, universal

Description:          An extensible, open-source system that manages the build 
                      process in an operating system and compiler independent
                      manner.  Unlike many cross-platform systems, CMake is
                      designed to be  used in conjunction with the native build
                      environment. The cmake release port is updated roughly
                      every few months.
