Can't (re)build pkg_chk after cvs up -A

This is on NetBSD 9.2 AMD65, in a virtualbox virtual machine.

This is a recent pkgsrc installation from June 12th which I have built a handful of programs (some emulators, mate-terminal, icewm and firefox) and that I've updated again today (June 20 2022) running "cvs up -A" in /usr/pkgsrc

I didn't have pkg_rolling-replace so I compiled/installed that after the update. I'm not sure how to use it, running just "pkg_rolling-replace" didn't change anything but i tried again following one of the examples

from the manpage and it seemed to fail on building pkgtools/pkg_chk

Here's the output:

beast92$ cd /usr/pkgsrc/;pkg_rolling-replace -rsuv

beast92$

I could easily be doing something wrong, particularly with pkg_rolling-replace which I'm not sure how to use.

Let me know if there's anything you'd like me to try
