Uninstall any PIP versions of these python packages, then install the NetBSD binary ones.
(Python packages needed for ueberzug)
pkgin in py38-pip py38-Xlib py38-Pillow py38-attrs py38-docopt
(Packages needed for ytfzf)
pkgin in fzf jq curl youtube-dl mpv
Patch (it should apply cleanly--there should be no *.rej files after the command), then compile ueberzug:
unzip -q ~/dl/ueberzug-master.zip
patch -p0 --posix < /tmp/ueberzug-master.patch
cd ueberzug-master
env CPPFLAGS=-I/usr/X11R7/include ./setup.py install
Install ytfzf and test everything out. If it works out OK, @pin or @nia can import it into pkgsrc.

I have other code which more closely imitates Linux (it returns the thread-name instead of the process-name like ueberzug seems to want), but, that is in C (and very different for each of the BSDs)--which means another module which will need to compiled and loaded. However this seems to work OK (so far) on all the BSDs all except OpenBSD, which has neither procfs nor /dev/pts 🙁.
