[one-users] [InM][I]: /usr/bin/env: ruby: No such file or directory

[Christophe Duez]

Hello there,
I'm new to opennebula and already had some install problems.
But now I can't find the solution.
I can add a host and get the list with onehost commands
but i don't get any information from that host.
i used the GUI as well as the CLI

this is my log file (oned.log)
can you help me?
