[Newbie] need help on /usr/bin/env: ruby : Permission denied (check)

Dear folks,

I got these error on following these guide:http://joemiller.me/2012/01/19/getting-started-with-the-sensu-monitoring-framework/

FYI: I’m running sensu sensu-0.10.2-1.x86_64 on RHEL5.7.

I’ve followed exactly from that guide. and all have been passed. and I get error on add a check section. really need some guide here, since I’m very new to ruby.

Rgds,

Feriyanto

Here is the error that I get from log:
