NetBSD 10 and opencv-3.4.17 pkg crash

Hello -- I have both a RockPro64 and Pinebook Pro running NetBSD 10 
GENERIC 64
[     1.000000] NetBSD 10.0 (GENERIC64) #0: Thu Mar 28 08:33:33 UTC 2024
[     1.000000] 
[email protected]:/usr/src/sys/arch/evbarm/compile/GENERIC64
[     1.000000] total memory = 3916 MB
[     1.000000] avail memory = 3774 MB

For both devices, using pkgin install opencv, with Python 3.11 
installed, I'm unable to import cv2:

Can anyone suggest how to further debug this?

This can be repro'd with latest from 
http://cdn.NetBSD.org/pub/pkgsrc/packages/NetBSD/aarch64/10.0/All.
