I recently built perl 5.32.1 with -DDEBUGGING

You built that -DDEBUGGING perl yourself ??
I took one look at the "config_args" as reported in the "perl -V" output you provided in your original post and decided that this must be a perl provided by FreeBSD Ports.
When I build perl on FreeBSD 12.0, I specify Configure args of "-des -Duse64bitall -Dprefix=/home/me/perl-5.x.y", and that's all.
If I wanted a DEBUG perl then I'd just be adding the "-DDEBUGGING" flag to the list I used. (It's a while since I've built a -DDEBUGGING perl, so correct me if there are other flags that need to be added.)

Try building your perl with a trimmed back list of configure args (like the list that I use) and see if that makes a difference.

How did you actually build and install DateTime-1.54 from source ? (Seeing the output from that process might be useful.)

Cheers,
Rob
