Ruby pkg add on for Linux Java Web EE 6.5 Installation - YAML ed pkg error

Hi,

Not sure this is something I need to report but I decided better to be 
safe. I downloaded 6.5 milestone 1 on Linux. I chose the Java & Web EE 
download. I then used the Plugins manager to install all the Ruby 
options. When the IDE restarted it reported that there was a problem 
with the YAML editor. It was expecting one version but found an earlier 
version (or the other way around). I am sorry that I didn't save the 
exact message. It didn't occur to me that I should mention this until 
after I dismissed the dialog box.
