Is this rails the one in /usr/bin?  XCode will use that one by default. 
In a terminal window, run:

type rails

to see.  If you are using Locomotive and have upgraded that to Rails 
2.0.2 then XCode won't see it.  In that case, in your terminal:

export PATH=/usr/bin:$PATH

and run the commands in the tutorial again to update RubyGems and 
Rails...

thanks
I believe it's not ,  so XCode is not using the right one...

yves$ type rails
rails is hashed (/usr/local/bin/rails)

so I updated usr/local/bin/rails (the one I was using with Tiger) and
XCode was using  usr/bin/rails...
got it .. up and running fine now

can I get rid off  usr/local/bin/rails  ??? I think so (?)

what did you do to get it working?

i ended up following the instructions here:
http://discussions.apple.com/thread.jspa?messageID=6893327 in order to
update the version that xcode is using, but i'd like to have xcode
point to /usr/local/bin/rails instead of /usr/bin/rails.
