I have been trying to understand RVM and decided to do so by not using it and seeing the consequences. I am trying to see how I can manage different versions of ruby and their gemsets without RVM.
I compiled Ruby 1.9.1 from source on my Ubuntu machine and found it in the path usr/local/bin/ruby.
Ruby: Denial of Service
So I was making a cgi ruby script and had the following at the top of the script file:
#!/usr/bin/env ruby
require 'rubygems'
require 'action_pack'
require 'cgi'
After a couple of hours of not getting "/usr/bin/env: ruby: No such file or directory" error and google searching, I uninstalled my system ruby 1.8.7 (I also had 1.9.3 installed via rvm) by doing sudo apt-get purge ruby rubygems.

I'll let the shell log explain itself:

Ruby, an object-oriented language for quick and easy programming, has just reached version 2.0.0.

Lately there have been a lot of one-liners posted in "ruby" on the apparent assumption that mainstream unix or Linux come with "ruby. They don't.
