I have two ruby installs on os X after migrating from tiger to leopard. The old one, version 1.8.5 is active and doesn’t work, the new one, version 1.8.6 is installed, but not active. How do I correct the situation?

This link helped me sort things out: [http://www.robbyonrails.com/articles/2008/01/22/installing-ruby-on-rails-and-postgresql-on-os-x-third-edition](http://www.robbyonrails.com/articles/2008/01/22/installing-ruby-on-rails-and-postgresql-on-os-x-third-edition) I renamed all copies of ruby essentially disabling them and then used the instructions on the site to reinstall ruby. ---

How do I correct the > situation? A common approach is to install in directories that reflect the version number, say ruby1.8.5 and ruby1.8.6, located wherever convenient, and then set /usr/bin/ruby to be a symbolic link to the required directory. Once the new version has been installed and tested, you change the link to point to the new directory rather than the old one. (If you subsequently have problems, it’s easy to revert!)
