Answer 1

• Dan Benjamin has some great instructions for compiling and installing Ruby, RubyGems and Rails into usr/local over at Hivelogic. This doesn't actually overwrite the system install of Ruby/RubyGems/Rails but rather takes precedence over it. Although the instructions cover Ruby 1.8.7, you can just update as appropriate for the 1.9.1 distribution.

• Alternatively, Ruby Version Manager (RVM) is a great way to manage multiple Ruby versions and associated gems. This Railscast episode has the details.

• You should be able to upgrade Rails to 2.3.8 using [sudo] gem install rails as usual.

Answer 2

I would recommend using MacPorts for most custom installs. It will install everything separately in /opt while keeping apple's original stuff intact. And also fetch any dependencies automatically.

For example, to install ruby 1.9.1 I would do port install ruby19 in the terminal and it would fetch and compile everything for me.
