Thank you for the feedback. I have made all five suggested changes. I noticed that my centos 6 environment did not have the %make_build macro so I defined it at the top of the specfile should it not exist at build time. The latest specfile can be found here: https://gist.github.com/knnniggett/cf2e4e2169ed8d4147b6367d6a60a843 Unless otherwise requested, I will wait for additional feedback before uploading a new RPM/SRPM.
