My hosting company recently upgraded their Rails version, so I want to  
freeze my app to Rails version 1.2.3. I was able to freeze it  
successfully, but when I try to start the server on my local  
development environment, I’m confronted with this error:

./script/…/config/…/vendor/rails/railties/lib/initializer.rb:43:in  
`send': undefined method`install\_gem\_spec\_stubs’ for  
#Rails::Initializer:0x290444c (NoMethodError)  
from ./script/…/config/…/vendor/rails/railties/lib/initializer.rb:  
43:in `run' from ./script/../config/boot.rb:46:in`load\_initializer’  
from ./script/…/config/boot.rb:38:in `run' from ./script/../config/boot.rb:11:in`boot!’  
from ./script/…/config/boot.rb:109  
from ./script/server:2:in `require' from ./script/server:2 from -e:4:in`load’  
from -e:4

Does anyone know what I can do to resolve this? Thanks.
