Answer 1

To uninstall from MacPorts:

port uninstall ruby

I recommend installing rvm and using it to manage all of your ruby versions. Start here: http://rvm.beginrescueend.com/

Once you have it installed, reload your shell and type:

rvm install ruby-1.9.2

Once that is done, type

rvm use ruby-1.9.2 --default

This will replace your system ruby with the rvm 192 version. Feel free to install any other versions and switch to them using rvm list and rvm use.
