carbon-cache.py binary fails to run

[Matt Conway]

If I run, /opt/graphite/bin/carbon-cache.py, I get the following trace, running /opt/graphite/carbon/bin/carbon-cache.py (note extra carbon directory level) works fine though.

Traceback (most recent call last):
  File "/opt/graphite/bin/carbon-cache.py", line 30, in <module>
    run_twistd_plugin(__file__)
  File "/opt/graphite/lib/carbon/util.py", line 62, in run_twistd_plugin
    config.parseOptions(twistd_options)

twisted.python.usage.UsageError: Unknown command: carbon-cache
