Unable to start OpUtils in Linux

Greetings!

I have installed OpUtils on CentOS 6.3 following the instructions available here for the bin file and the missing libraries. When I try to run ./startOpUtils.sh I get the error below. I have attached a system profile.

Thanks for your help in advance.

System:
