Thanks to everyone who responded.
I had the correct Tivaware installed.
It was about a week ago that I reported the problem, and I do not recall why the projects were not appearing in the work space after following the instructions in the above reference tutorial document. I recall there were was an error message of some kind. But, it might have had to do with the fact, that despite what the instructions say, there is no grlib file in the 1.0 folder. I ended up installing everything from the newer version folder after updating the compiler. That probably did it.
The driverlib and glib items still are in error but that will probably be fixed by installing the cortex stuff.
And, deleting the tm4c123gh6pm_startup_ccs.c file does allow a project to build without error and run on the board.
