cloudfoundry_controller cannot start
===

I want to ask something about cloudfoundry .. 
I installed cloudfoundry on my local sytem using this tutorial .[how to install cloudfoundry server paas][1] from ppa repository on ubuntu 12.04 .

Then i run it with syntax : **$ sudo /etc/init.d/cloudfoundry-server start**  
and the result is :

router              :	 RUNNING

cloud_controller    :	 RUNNING

dea                 :	 RUNNING

health_manager      :	 RUNNING

But when i restart ,it said that cloud_controller STOPED

The I restart it manually from syntax : **$ /opt/cloudfoundry-server/vcap/bin/cloud-controller restart** 

and the result is : 
**Staging environment validation failed: sinatra runtime ruby18 version was 1.9.3p0, expected to match 1.8.7***

Can anybody help me ? please ??
