xemacs fails to install, won't coexist with emacs

I tried repeatedly to install xemacs, including removing all ports and reinstalling, per the major system upgrade instructions. I always get the same result:

[MacBook-Pro:~] kristen% sudo port install xemacs

If I install regular emacs, which installs successfully, I get this:

[MacBook-Pro:~] kristen% sudo port install xemacs
--->  Computing dependencies for xemacs
Error: Can't install xemacs because conflicting ports are active: emacs
Error: Follow https://guide.macports.org/#project.tickets to report a bug.

I'm on Catalina, build 19B2106.

In the future, please use WikiFormatting, fill in the Port field and add the port maintainer(s) to Cc (port info --maintainers xemacs), if any.
