"ImportError: No module named pbr" when creating Fuel ISO

[Claude Durocher]

I'm trying to build ISO from source and I'm getting the following error :

...
mkdir -p /root/fuel-main/build/packages/rpm/sources/fuel-agent
cd /root/fuel-main/build/repos/nailgun/fuel_agent && python setup.py sdist -d /root/fuel-main/build/packages/rpm/sources/fuel-agent
Traceback (most recent call last):
  File "setup.py", line 17, in <module>
    import pbr
ImportError: No module named pbr
make: *** [/root/fuel-main/build/packages/rpm/sources/fuel-agent/fuel-agent-0.1.0.tar.gz] Error 1

Steps to reproduce :

-fresh install of Ubuntu 12.04 server (current cloud image used)
-build according to doc :

apt-get install git
git clone https://github.com/stackforge/fuel-main
cd fuel-main
./prepare-build-env.sh
make iso

Expected result :

No compilation error

Work around :

cd build/repos/nailgun/fuel_agent/
pip install -r requirements.txt
cd -
make iso

Please, provide info what branch are you use for iso build.

I first tried the default (master) then tags/5.1 with the same result.
