Can run up the server after update to 2.3.2

my rails version was 2.2.2 and I turn 2.3.2 last night with gem update
and rake rails:freeze:edge. unfortunately I got a problem when I restart
my server.

a error when I script/server

./script/…/config/…/vendor/rails/railties/lib/rails/plugin.rb:1:in
require': no such file to load -- active_support/core_ext/kernel/reporting (LoadError) from ./script/../config/../vendor/rails/railties/lib/rails/plugin.rb:1 from ./script/../config/../vendor/rails/railties/lib/rails/plugin/loader.rb:1:inrequire’

from ./script/…/config/boot.rb:11:in boot!' from ./script/../config/boot.rb:110 from script/server:2:inrequire’
from script/server:2

and I tried to run rake rails:update, also a problem.

rake aborted!
undefined method `mattr_accessor’ for ActiveSupport::Dependencies:Module

Do you have any idea waht’s going wrong?
