Well, as no one has been able to offer any suggestions, I kept trying. And I now have the UPS module installed, but none of the shipping options show up in the cart. I made one change to my php settings. I turned on allow_url_include. This seems to have done the trick.
Now, to figure out why the UPS shipping options are not in the cart. Country, state, zones, etc are all set up and active. But am sure something is not right to block every UPS option.
