Homebrew Python Fab can't see yaml

Question

I've installed several different versions of PyYAML at this point and in no instance does Fab see YAML.

I've done brew install libyaml and pip install pyyaml and in neither instance does fabric see the yaml module.

When I import YAML in Python, it works right. The result for import yaml and then print(yaml) is:

<module 'yaml' from '/usr/local/lib/python2.7/sitepackages/yaml/__init__.pyc'
