The config.guess and config.sub files in your repository are ancient, resulting in configuration failure on Apple Silicon computers:

https://build.macports.org/builders/ports-13_arm64-builder/builds/26588/steps/install-port/logs/stdio

checking build system type... configure: error: /bin/sh ./config.sub -apple-darwin22.5.0 failed

Please remove these files from your repository so that when the bootstrap script runs autoreconf it will copy in new versions. The install-sh script is also recreated by autotools and the old version in the repository should be removed. This would complete the work started in #2.
