"Internal Server Error" for coordinates2politics on AMI

[modulitos]

The following command works on the site at datasciencetoolkit.org:
curl "http://www.datasciencetoolkit.org/coordinates2politics/37.769456%2c-122.429128"

But when I deploy the AMI to my site, (using the US-West AMI id: ami-771e3f47), the same call gives me a 500:
curl "http://my-dstk.example.com/coordinates2politics/37.769456%2c-122.429128"

The curl command was used in the docs here: http://www.datasciencetoolkit.org/developerdocs#coordinates2politics

and I deployed my AMI from the docs here: http://www.datasciencetoolkit.org/developerdocs#setup

@modulitos did you figure out what the error was? I have a colleague creating a server from this AMI and I cannot easily check its error log
