Sounds like you don't have the 'logfile' parameter defined in your
config.yaml. Set the following:

logfile: /tmp/changebyus.log

just to verify this. The "KeyError" is coming right after
Config.get('logfile'), so that's why I'm inclined to say the above.

Thanks! That was the issue. The comments in config.yaml.sample didn't specify what to supply for the 'logfile' parameter so I had commented it out. Would it be possible to change the sample file to contain a default value for the 'logfile' parameter and update the comments to make it apparent the parameter is required?

The idea is to have everything come from an rcfile and to use fabric for deployment. This is why there are no default values (only interpolation variables) in the config.tmpl file. A sample rcfile is provided at rcfile.sample.
In order to use fabric to create a local config file, do:
fab -f fabfile.py --config=/absolute/path/to/rcfile dev clean_build bundle_code create_local_configs

Once this is done the first time, you can omit the "clean_build" task. For a list of tasks and their descriptions, look at
fab -f fabfile.py --config=/path/to/rcfile -l

I also noticed that there were a couple of variables missing from rcfile.sample, and have added them into the develop branch. And I just noticed that there's no documentation about this fabric-related process in the wiki. I'll add that too.
