Playerctl failed Port

Hello I am trying to port playerctl version 2.3.1 on OpenBSD and I get an
error when I try to do a "make makesum" on step 5 of Porting Checklist in
OBSD documentation.

For reference here is the Documentation I am following and the problematic
makefile as well as the link of the project that I am trying to port.

Project that I am trying to port: https://github.com/altdesktop/playerctl
Documentation: https://www.openbsd.org/faq/ports/guide.html

Makefile is attached in email.

Thank You,
Lewis I.
