how to upgrade the ruby version from 1.8.7 to 1.9.3 on site5.com

Question

Hi I am wanting to install my website on a site5.com website but I am having difficulty. The ruby version on the actual site is 1.8.7 but the ruby version I use on my local computer is 1.9.3. How do I upgrade to ruby 1.9.3 without the use of sudo, apt-get install, and apt-get update?

If anyone knows some ways to get in without having to use sudo or the above, I would be very greatful for an answer to this problem.

Basically, I don't think you can at the moment. But as of a few weeks ago, it looks like they're starting to convert to 1.9.3 (emphasis added):

We will begin the process of updating all servers to a newer version of Phusion Passenger (the 4.0 branch) in November. That deployment will allow you to use any version of Ruby — including 1.9 and 2.0 — inside your Rack-based applications (eg Rails).

We will then begin work on changing the default Ruby across our entire fleet from Ruby 1.8.7 to 1.9.3. You will receive ample notification for this change, but if your application only functions on Ruby 1.8.7, you will be able to change the Ruby version per-application and per-account (via .htaccess) using the PassengerRuby option available in Phusion Passenger 4. You can then compile your own version of Ruby 1.8 inside of your account for your legacy applications.
