Rails on Mac OS X Leopard...

A few days ago I got a new Macbook Pro (yippie!). Until now, I was
using Instant Rails on Windows. I am now trying to get my rails
projects to run on the MBP having copied them from Windows.

From the terminal window, I can see that Rails and Ruby are installed
as advertised (--version works). For now, I am happy wth Ruby 1.8.6
and Rails 1.2.6 that are on there. HOWEVER, when I try "ruby script/
server" or "ruby script/console" I keep getting the following error.

Cannot find gem for Rails ~>1.2.3.0:
    Install the missing gem with 'gem install -v=1.2.3 rails', or
    change environment.rb to define RAILS_GEM_VERSION with your
desired version.

What am I missing? Isn't all the "basic" stuff preinstalled out of the
box? The project I am trying to run is very simple - no fancy gems or
anything. It was also built using 1.8.6

I read this http://developer.apple.com/tools/developonrailsleopard.html
but its trying to get me to update and I'd like to stick to 1.8.6 and
1.2.6 since some of my other projects are based on that.

Thanks, Roupen N.

Your environment.rb states Rails 1.2.3 as the version to look for, just change it to 1.2.6 and you’re done.
