Service won't start on Amazon Linux AMI release 2016.03

[Breeze773]

I am attempting to test out the CF example template to use some cfn-init and cfn-signal commands to handle mounting and unmounting volumes within cloudformation.
I have an rpm command to install the cfn-resource-bridge rpm in my cloudformation template. The install of the code works, but when the service attempts to start I get the below error.
I have installed the prereqs for this code. It appears that this new package is not in the OS's default library path. I'm not a python export so not sure how to fix this within my cloudformation templae.

This is the output in /var/log/cfn-init.log

/etc/init.d/cfn-resource-bridge start also outputs the same error.

Thanks in advance for any help on this. -Chris

I had the same issue. I found that I needed to install python26 and made sure that the library was installed at the right location. I am now hitting other issues because cfn-resource-bridge was written a long while ago and apparently was not updated since then.
