[chef] installing 0.9.6 on CentOS 5.4

[< >]

I am trying to install chef 0.9.6 on the CentOS 5.4  environment. I've 
manually
installed couchdb, erlang and rabbitmq and now trying to bootstrap chef ruby
gems.
I've commented out the rubbitmq java and couchdb recepies from the chef 
bootrap
cookbook (because I've some problem with erlan package) and now I'm trying to
run the cookbook but getting the following error:
