Problems with latest and greatest?

Rails
1

I just did the following:

  1. checked out latest rails from svn.
  2. built project using the /bin/rails with the latest rails binary.
  3. did a “rake freeze_edge” within the project

Now, script/server is failing

./script/…/config/…/vendor/rails/railties/lib/commands/…/tasks/tmp.rake:1:
undefined method namespace' for #<Object:0x401ce970> (NoMethodError) from ./script/../config/../vendor/rails/activesupport/lib/active_support/dependencies.rb:142:inload’
from
./script/…/config/…/vendor/rails/railties/lib/commands/server.rb:29
from script/server:3

I am running Rake 0.7.0…
Any ideas ?
