activesupport

Hi guys. I'm having a problem using ActiveSupport's core extensions on a gem I am developing.

I had it working with AS 2.3.8, but as soon as I wanted to port it to 3b4, the extensions stopped working and my test results are filled with lines such as:

undefined method `blank?' for "something":String

I've included it via gem "activesupport" followed by require "active_support"

Is there anything else I need to call to include those extensions?

Thanks
