Comment 1 for bug 888385

The original problem is a little farther up that log:

Obtaining quantum from git+https://github.com/openstack/quantum.git#egg=quantum (from -r /home/rneff/OpenStackDashboardSrc/horizon/openstack-dashboard/tools/pip-requires (line 22))
  Cloning https://github.com/openstack/quantum.git to ./.dashboard-venv/src/quantum
  Found command 'git' at '/usr/bin/git'
  Running command /usr/bin/git clone -q https://github.com/openstack/quantum.git /home/rneff/OpenStackDashboardSrc/horizon/openstack-dashboard/.dashboard-venv/src/quantum
  Running setup.py egg_info for package quantum
    Checking for virtual-env and easy_install
    done.
    Command 'egg' not found

It's actually not a problem in Horizon that killed it. It's quantum's setup.py that's dying for you.

FWIW, in the last week Horizon's environment installation has been cleaned up a fair bit. I can't say that it would succeed for you, though, as the problem lies in another project.

You should probably connect with the Quantum guys to help them get their setup.py working on RHEL.

If it turns out I'm wrong feel free to re-open this bug.
