You might like to get an account at ruby-versions.net, which will give you
an account you can ssh into and play with different versions of Ruby all the
way back to 1.0

http://www.ruby-forum.com/topic/212951

I don't find that I use it often, but it's a nice way to play around with
the language, without needing to know how to set all that stuff up yourself.

Don't do this, you could break anything that depends on it being there.

At your terminal type: whereis ruby

This will look in some common locations that binaries are installed to, it
will return your system Ruby. On mine (Snow Leopard) it says /usr/bin/ruby

Also useful is: which ruby

This returns the first match it finds at the directories specified in your
$PATH variable (you can see what this looks like by doing: echo "$PATH"),
which defines locations to look for binaries when you execute them in the
terminal.

You could just put this into a local dir like ~/bin (and make an alias, or
not use a suffix) then make sure it's earlier in your $PATH so you get to
use your Ruby, but other programs that depend on the system Ruby aren't
altered. This is how I dealt with it at school, where I couldn't save
outside my home directory, and it's basically what RVM is doing when you
install it locally, anyway.
