Thanks for your patience JJ; I went from start to end and it worked!

Then I pulled up the backup and they had no true functional
difference.  Not believing this could be the case I used my old test
cpp file against the new package and it failed!  Used the new test cpp
against the old package and it worked!  The problem was in the test
cpp file all along.  (Color me chagrined.)  It seems I had omitted the
final ']]' from the Rcpp::depends line and since it is a c++ comment
line obviously no syntax error was thrown.

Thanks again for the help, at least I got to learn more about how the
attributes work. :)  That example worked well as a comparative

Now, back to the regularly scheduled programming.
