[emacs-w3m:13698] Problems installing emacs-w3m

I'll start by confessing I'm new to emacs and I don't know lisp or any programming.
I'm running OpenBSD-6.8-current on a Thinkpad X220. Emacs version 27.1, 
w3m version 0.5.3+git20200502.

Trying to install emacs-w3m via MELPA (M-x package-install RET w3m RET) 
gives me:
