At a friend's suggestion, I tried out the i3 window manager.
At first, it simply failed to run and I thought, "Wow. That's really minimalist!"
Then, after a little troubleshooting, I tried
sudo ln -s /usr/local/lib/libev.so.4 /usr/local/lib/libev.so.3
sudo ldconfig
That allowed i3 to run but I couldn't get any of the key bindings to actually do anything.
I note that libev.tcz was updated from 3.9 to 4.33 last May whereas i3.tcz was last updated in 2015.
I mention this only as matter of general interest - I have no actual intention of using i3, having realized that it's a
-tiling- window manager.

Per the same thread, @jshorthouse - did you have any luck with an i3 update?
