John,
Run this first --
python f5-openstack-agent-dist/scripts/universal_truth.py

Then run --
f5-openstack-agent-dist/scripts/package_agent.sh "redhat" 7

Sorry, we need to add a package section to the README to make this clear. The universal truth script was written to avoid issues where we had dependencies specified in a bunch of locations.

Hi @jgruber,

I've got:
https://github.com/F5Networks/f5-openstack-agent/blob/master/.travis.yml#L32

Creating this file for you dynamically based upon the file:
https://github.com/F5Networks/f5-openstack-agent/blob/master/setup_requirements.txt

So this should work for you if you issue:

./f5-openstack-agent-dist/scripts/universal_truth.py
./f5-openstack-agent-dist/scripts/package_agent.sh "redhat" "7"

This will generate your .rpm file under:
./f5-openstack-agent-dist/rpms/builds/

Proof:

$ python ./f5-openstack-agent-dist/scripts/universal_truth.py

This does require docker, and it reduces our requirements to a single file, setup_requirements.py (thus universal_truth). The thing I forgot to do was set things up for setup.py to use the setup_requirements.py, but this is a quick and easy thing to do. There's a ticket open to handle fixing this aspect.

Thanks,
