Multiple make-time errors under Linux version 2.6.32-642.15.1.el6.x86_64

I am trying to build this tool under Linux version 2.6.32-642.15.1.el6.x86_64 (mockbuild@c1bm.rdu2.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) ) #1
SMP Fri Feb 24 14:31:22 UTC 2017

I get multiple make-time errors:

Subdirectory 'graph' appears to be empty; are there prerequisites missing from this distribution?
