Ruby fails after installing custom cartridge for OpenShift

Question

So I am trying to install a custom cartridge that has python3.5 https://github.com/Praisebetoscience/openshift-cartridge-python-3.5

The command I'm running is:

rhc app create bot nodejs-0.10 http://cartreflect-claytondev.rhcloud.com/github/Praisebetoscience/openshift-cartridge-python-3.5

However after instalation of the cartridge completes ruby crashes with a strange error. I'm not really familiar with ruby and I'm not sure why this is coming from core library. Do you know what is causing that?
