[ESS] Issue with polymode installed from ELPA

[Sparapani, Rodney]

Hi Gang:

I am stumped.  I tried to install polymode from ELPA into Vincent Goulet's
distro of Emacs and ESS (it no longer contains polymode sadly).  
macOS 10.14.4 Mojave, Emacs version 26.2 and ESS version 18.10.2  
The ELPA install seemed to go well.  My load-path starts with
("/Users/rsparapa/.emacs.d/elpa/poly-R-0.2" 
"/Users/rsparapa/.emacs.d/elpa/poly-markdown-0.2" 
"/Users/rsparapa/.emacs.d/elpa/markdown-mode-2.3" 
"/Users/rsparapa/.emacs.d/elpa/poly-noweb-0.2" 
"/Users/rsparapa/.emacs.d/elpa/polymode-0.2" ...
So, everything looks good.  But, I get errors when I put simple requires in 
.emacs like (require 'polymode)
So, I hard-coded all of the paths, but this gets hairy since now I have to 
hard-code all of the dependencies too ...
(require 'polymode-classes "~/.emacs.d/elpa/polymode-0.2/polymode-classes.el")
(require 'polymode-core "~/.emacs.d/elpa/polymode-0.2/polymode-core.el")
(require 'polymode-compat "~/.emacs.d/elpa/polymode-0.2/polymode-compat.el")
(require 'polymode-methods "~/.emacs.d/elpa/polymode-0.2/polymode-methods.el")
(require 'polymode-export "~/.emacs.d/elpa/polymode-0.2/polymode-export.el")
(require 'polymode-weave "~/.emacs.d/elpa/polymode-0.2/polymode-weave.el")
(require 'polymode-base "~/.emacs.d/elpa/polymode-0.2/polymode-base.el")
(require 'poly-lock "~/.emacs.d/elpa/polymode-0.2/poly-lock.el")
(require 'polymode "~/.emacs.d/elpa/polymode-0.2/polymode.el")
(require 'poly-noweb "~/.emacs.d/elpa/poly-noweb-0.2/poly-noweb.el")
(require 'poly-markdown "~/.emacs.d/elpa/poly-markdown-0.2/poly-markdown.el")
(require 'poly-R "~/.emacs.d/elpa/poly-R-0.2/poly-R.el")
Getting the order of the dependencies right was a pain as well.  However, 
brute force fixed it!  But, I don't want to go through this ever again for
obvious reasons.  It took me over an hour for what is supposed to be a 5 or
10 minute install.  Does anyone have an idea of WTF is going wrong here?

Thanks,

Rodney
