Hi,

I'm trying to update my ros/orocos workspace with the information from here
:
https://github.com/orocos/rtt_ros_integration/blob/hydro-devel/README.md
And orogen is not detecting my ruby version (I'm on debian jessie).

Is the documentation up to date ? should I select a particular version of
ruby ?
