Thanks.  But I note that those are all for very old, EoL'd versions
of Fedora.

I manually installed cython with pip, but then the kivy install
failed with some C errors.  At the top of it's multi-thousand line
log output was a warning that it requires cython-0.21.2.  Pip had 
installed cython-0.23.  I installed cython-0.21.2 (since I do not 
use cython for anything else and noting that pip did not bother 
to inform me it was overwriting an existing install) and then pip 
installed kivy without error.  However there were a number of 
warning message about missing somethings (libs or python packages, 
was not clear to me).

So I eventually found the kivy docs on their website where they
list prerequisite packages for installing kivy on ubuntu.  I'll 
translate those to hopefully the equivalent fedora package names, 
install them, reinstall kivy, and get a working kivy install.

The point here that all the above is a LONG way from what was
was posted here: "just type 'pip install kivy' and pip will take 
care of everything".

I hope someday Python gets a decent packaging/distribution story.
