nmap @7.95 cannot compile on macOS 15 Sequoia

[SaintBol]

Using Xcode clang compiler (Command Line Tools not present): cannot compile the port on macOS 15 Sequoia. Compiling with openssl installed.

Attached main.log

Error is a bit obscure («command failed»):

:info:build Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_net_nmap/nmap/work/nmap-7.95" && /usr/bin/make -j16 -w all 
:info:build Exit code: 2
:error:build Failed to build nmap: command execution failed

Therefore I tried manually in the build directory just after the error:

It complains about aclocal-1.16 not being there, whereas aclocal-1.17 is actually there...

% port content automake | egrep 'aclocal-.*[0-9]{2}$'

FWIW, I just upgraded and build nmap locally without seeing this issue. I'll look some more once my normal set of installed ports finishes installing.
