You are correct, there is a bug there. We have been changing the ruby  
API a bit broke the history. That is already solved in the svn. http://trac.opennebula.org/changeset/17

I encourage you to get the source from subversion and update from time  
to time. The good thing is that the script that installs it makes  
links from where the source files are so ruby files are automatically  
updated when you download new changes. Also recompiling makes  
executables in the installation directory updated.

Configuration files are copied so you wont loose any. It was made like  
this to make developing and testing easier. There will be a real  
installation procedure when it reaches an stable version.

Sorry for the inconveniences.
