making ruby 1.9 default on os x [duplicate]

Question

How do I make ruby 1.9 the default version to use instead of the 1.8.x that is by default installed on os x?

Thanks.

As of v2.1.3, the "correct" MacPorts way of setting a specific version of a package as the default is to use the select command, like this:

sudo port select --set ruby ruby19

There doesn't appear to be any documentation about this command in the MacPorts Guide. You can however run port help select to get a very limited description. This functionality replaces the +nosuffix "variant" style of setting the default version.
