Thank you.  That didn't get me there, but I really appreciate the quick 
response, and that actually helps me in some other areas.

I got this:

root@rockhopper:~# update-alternatives --config ruby
update-alternatives: error: no alternatives for ruby.
root@rockhopper:~# update-alternatives --config rubygems
update-alternatives: error: no alternatives for rubygems.
root@rockhopper:~#

rvm in that guise is not on my apt purvey.  I appreciate the suggestions. 
Perhaps if it's this hard it's better to wait for the OSs to upgrade themselves 
anyway.  I just noticed the CentOS we use is way back to ruby 1.8.5.  I sure 
hope we stop using CentOS soon.  It is a dog, and wastes a lot of our time. 
Debian family stuff has it's problems, but for my work it seems to always come 
out as superior.
