xemacs @21.4.22: fails to configure on Monterey

[wealthychef1]

My machine is running Monterey. I just bought it.

root@MBP-2021 (~ ): uname -a
Darwin MBP-2021.hitronhub.home 21.1.0 Darwin Kernel Version 21.1.0: Wed Oct 13 17:33:01 PDT 2021; root:xnu-8019.41.5~1/RELEASE_ARM64_T6000 arm64

I tried to install xemacs with macports 2.7.1 and this happened:

Here is the first error in the log:

I'm attaching the full log file, it's pretty short.
