Re: JRuby support

[David Ekhaus <dekhaus@mac.com>]

Fair enough (regarding the linux only comment) - here's what I get when I run 

> ruby setup.rb

on RHEL 6.2 …

no ruby extention exists: 'ruby setup.rb setup' first
Try 'ruby setup.rb --help' for detailed usage.




	The message …

		"no ruby extension exists: 'ruby setup.rb setup' first" 

	leads me to believe that it the command 'jruby setup.rb' didn't work properly.

	If it (the 'jruby setup.rb' command) did work properly - then can someone advise me on what the next step(s) are.

	If it didn't - similarly, can someone advise me on what I need to do to get it to work.

Thanks
Dave
