I started using Rails after Tiger came out so I haven’t been through a  
major upgrade since using it.

I’m a little concerned on what upgrading will do to my development  
environment. I even heard that the new OS would even have Rails  
already installed on it, but I don’t want it to overwrite the versions  
I have installed already.

Is there any advice and what I need to do in order to prepare for the  
upgrade?

Thanks.

Leopard will have Ruby 1.8.6, Rails 1.2.x, Mongel, Capistrano and  
Subversion pre-installed as “first-class” citizens into the OS core.  
Meaning they don’t live in /usr/local nor /opt directories. I believe  
they are installed in /bin. So you shouldn’t have to worry about it  
overwriting your installation. Just make sure your install directory  
shows up before /bin in the system $PATH environment variable.

That being said, given that Leopard will include nearly the latest  
releases of Ruby (and not a broken one) and Rails with most of the  
standard goodies, why not just use them. If they are not completely up  
to date just use RubyGems to update them. This is what I’ll do once  
Leopard is released. Heck as much attention as Apple is putting into  
Rails these days, we just might see them upgrade as Rails does with  
the standard software update mechanism (one could dream anyway).
