To reproduce:

• Uninstall Maloja (pip uninstall maloja)
• Check out the branch 'issue_026_evolve_builder_module'
• Install Maloja (pip install .)

Run the 'build' command:

start %HOME%\py3.5\scripts\python -m maloja.main @options.private -v --log=run.log build --input=maloja\test\issue_025-02.yaml

IpAllocation mode was set to POOL, requiring a static IP pool. Setting one up eliminated the error.

In practice, IP allocation is defined as MANUAL, making this issue less common in our case.
