Hi,

I am very new to ruby and have hit a wall with the installation. I am  
using a Mac OS X 10.4.11(Tiger). I got everything installed correctly  
(Ruby Version 1.8.6, RubyGems 1.3.2, Rails Version 2.3.2, db adapter  
sqlite3) and I was trying to work through the Agile Web D. with  
Rails 2nd edition. There was an issue with scaffold being deprecated in  
newer versions so I scoured the web to find a fix. I tried to uninstall  
RubyGems 1.3.2 so that I could work through the book edition 2 with the  
intention of installing the newer version later. However now when I try  
to start the server I get the message

Rails requires RubyGems \>= 1.3.1 (you have 0.9.2). Please `gem update --system` and try again.

and when I try to update my gems or indeed run any other gem command I  
get the error

/usr/local/lib/ruby/site\_ruby/1.8/rubygems/source\_index.rb:92:in  
`load_specification': private method`specification\_version=’ called for

`manage\_gems’

I’m really at a loss so any help would be greatly appreciated. Please  
bear in mind that I am very new to Macs and Ruby.

Kind regards,
