ERROR NameError: uninitialized constant ActiveSupport::Dependencies

Hello all,

I keep getting the following error after visiting 127.0.0.1:3000 on a
fresh rails 3.0.6 install with ruby 1.9.2. I have tried googling
solutions but most results are addressing the issue in rails 2 and
suggest adding ‘require “threads”’ to the boot.rb; this did not resolve
my issues.

Any suggestions on how to resolve this or where to start?

Can you post a gem list for the RVM environment you are trying to run
this
in?
