undefined method `devise'

I am getting the following error when trying to run migrate for the first time.

undefined method `devise' for #<Class:0x00000102d10f30>

I think this issue was already raised as issue #21, but for some reason github gives a 404.

I am using ruby 1.9.2 with rails 3.1.

thx!
