cpuminer json rpc call failed
You should sign up for a pool service and configure minerd to send shares to that service.  Right now it is attempting to connect to a local instance of a scrypt coin (litecoind I would presume) on port 9332 for solo mining.  If that is what you intended then verify that you have a server running and listening on that port.  It is also not recommended to run minerd as root in case theres is a remote buffer overflow vulnerability in the application.  You can check by executing the following command:

netstat -anp | grep 9332


This will tell you what application had that port open if any does.
