[one-users] sunstone-server start error

[Mario Sickert]

Hey,

Got still problems after install Sunstone.

one service is running with oneadmin, but after trying to start 
sunstone-server i got an error.
Syntax looks like this:

$sunstone-server start
Stale .lock detected. Erasing it.
Error executing /usr/share/opennebula/sunstone/sunstone-server.rb, 
please check
     the log /var/log/one/sunstone.log

this is the logfile:
/usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in 
`gem_original_require': no such file to load -- CloudAuth (LoadError)
     from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in 
`require'
     from /usr/share/opennebula/sunstone/sunstone-server.rb:52

Mario
