Sure!, thank you for your response.  I confirmed that on CentOS 6 I'm getting:
   library: |built-in|

But on CentOS 7, I'm getting as you indicated:
   library: |/usr/local/lib/gtags/exuberant-ctags.la|

The reason I started using global is for the reference tag look ups so
ctags is definitely not the parser I want to use and apparently the
"built-in" parser is the one I want.

Is my build incorrectly configured to use the ctags parser by default
instead of the built-in parser?
How do I force the use of the built-in parser?
