The Ubuntu way is to run 'sudo update-alternatives --config ruby' and
'sudo update-alternatives --config rubygems', or instead of calling Ruby
scripts with 'ruby', call them with 'ruby1.9' when you want them run in 1.9.

Another solution that is available is Ruby Version Manager (RVM).  I've
never used RVM, so I can't say anything for or against it.
