OK, I figured out...

The import statement needs to look like this:

"from ec2list.panel import EC2ListPanel"

I was just using "from ec2list import EC2ListPanel" which was insufficient since it has an empty __init__.py 
adding the ".panel" (which you suggested in your original email, but I didn't quite grok it the first time) fixed it.

The register statement in overrides.py looks like:
try:
        settings.register(EC2ListPanel)
except Exception as exc:
        LOG.debug("Error registering panel: %s" % exc)


Now it's working.  Thanks for the help.
