pcre @8.45: fatal error: 'cassert' file not found

[FuturePilot (Nick)]

pcre fails to build on macOS 15 with the following error

Failed to build pcre: command execution failed

It looks like it's failing on this step

:info:build Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_pcre/pcre/work/pcre-8.45" && /usr/bin/make -j20 -w all
:info:build Exit code: 2
:error:build Failed to build pcre: command execution failed

I have attached the full log.

Trying to manually run the make command above fails here
