Transferring Rails Installation to new Macbook

I just got a new Macbook and transferred all my files from my old mac
onto it. Looks like rails didn't make the cut. Is there a way to
transfer rails over or do I have to re-install from the beginning?



If you are fine with the standard 1.8.2 ruby, then just do "gem
install rails -y" and it should be there. If you need a newer ruby
then install the full stack in a new directory from sources. Then you
have "TOTAL CONTROL(tm)"

This page has step by stem instructions that worked quite well.
Realize that you need to put src/bin on your path so it overrides the
default ruby location.

I put the src directory under my user home so it will always move with
me in the future.
