uninitialized constant error

[davidimoore]

I added this gem, installed it and after starting up my rails server I get the following error:

active_admin_importable-1.1.2/lib/active_admin_importable.rb:5:in `<top (required)>': uninitialized constant ActiveAdmin (NameError)

I'm using rails 3.2.3

Can you provide more of the stack trace as well as an example of one of the admin files? Also, your gemfile would be very helpful.
