It doesn't seem I have or ever had PyPy, but I could've if something 
else required it a long time ago.
After a recent 'sboupgrade --all' letsencrypt is now working.
I also uninstalled an old Python setup tools package I had from 
Slackware 14.1 that I already deleted from my main saved packages 
directory, but that uninstall might've been on a different server. I was 
just checking letsencrypt on both, and it was working on one.
So I don't really know why it's working now...
