TypeError: object is not a function (/usr/share/statsd/node_modules/statsd-ganglia-backend/statsd-ganglia-backend/index.js:249:3)

Installing statsd-ganglia-backend as documented in the README.md I get the following error while configuring my statsd server for sending metrics to ganglia via this backend.

8 Dec 18:37:50 - trace: TypeError: object is not a function

NOTE: I modified the logging to include the stacktrace from the exception that is caught.

- util.log("Exception: " + e);
+ util.log("trace: " + e.stack);

After looking at what was different between 0.2.1 and master I chose to do a custom npm install on the master branch of this repository... and that seemed to solve this problem I was facing

installation instructions

root@server:/usr/share/statsd/node_modules$ sudo npm install jbuchbinder/statsd-ganglia-backend

check that ganglia is now getting published metrics
