I ran through the steps. I had to skip the 'git checkout stable-2.0.1' command. I got the following error:
it checkout stable-2.0.1
error: pathspec 'stable-2.0.1' did not match any file(s) known to git.
Regardless, I skipped the step, proceeded to the next step, built and installed the RPM successfully.
Thanks for making this easy. I was looking for the RPM but apparently it is not yet released.
