If I go into irb in rails3 beta3 and type in require ‘activesupport’  
it says:  
LoadError: no such file to load – activesupport

What is the problem? Have I done something wrong?

Bundle show activesupport works properly and tells me where the gem  
is!

I think I have found the answer.

1. It first require rubygens to be loaded
2. rails3 has deprecated activesupport and requires active\_support
