CLSI on ubuntu 11.10 / 12.04 (EC2 instance) using chef [closed]

Question

I'm trying to install CLSI on ubuntu 11.10 using chef (see: https://github.com/scribtex/clsi-chef).

I'm trying to get a CLSI server up and running but I'm not able to :( Getting:

================================================================================
Error executing action `install` on resource 'package[libreadline5-dev]'

Is anyone able to successfully install it?

I have added nginx-passenger in clsi.json so the line looks:

"run_list" : [ "mysql::server", "mysql::client", "nginx-passenger", "clsi" ]
