New question #169644 on Graphite:
https://answers.launchpad.net/graphite/+question/169644

Hello,

I am following the Graphite installation instructions here:
http://graphite.wikidot.com/installation

I have completed the first page, and when I run ./examples/example-client.py, I get the error:
Couldn't connect to 127.0.0.1 on port 2003, is carbon-agent.py running?

I have started Carbon (or at least I tried to):
cd /opt/graphite/
./bin/carbon-cache.py start

It seems, however, that this does not start carbon.  Tracing through the logs in /opt/graphite/storage/log/carbon-cache/console.log, I get the error:
AttributeError: 'module' object has no attribute 'parseRetentionDef'

The entire traceback is below.  Any help would be appreciated.
