And after that you include with #include <readline/read line.h> #include <readline/history.h>

fatal error: 'editline/history.h' file not found

Any advice would be greatly appreciated.

Other problem is that the code won't work with this library. You need to rework it using the following example: http://www.cs.utah.edu/~bigler/code/libedit.html

There's a lot more to set up and tear down when using the Mavericks' editline; it's not so user-friendly for a beginner as the code in the example.
