create an alias or symlink for at least one of them and have them in  
different directories
If you create a symlink for 1.9 called ruby19 you can call the 1.9  
interpreter with
ruby19 script_name.rb

Likewise you could create ruby18 for 1.8
That's the easiest way to do it, and common with other software such  
as PHP 4 or 5 on the same system.
Usually, people leave one of the two installations as the default  
with simply PHP
you can do this with Ruby too.

With Ruby Gems you might run into some trouble though.
