Update to Commerce shipping 2.x breaks site with WSOD Implementing shipping 2 is becoming a bit more troublesome than i had anticipated.

Right now, I am getting the following error on a White Screen of Death when I install commerce shipping 7.x-2.0-beta1

Fatal error: Call to undefined function commerce_shipping_services() in /var/www/html/nidadev/sites/all/modules/contrib/commerce_shipping/commerce_shipping.rules_defaults.inc on line 44

I am not sure what to make of this Is there something obvious that I am missing?

Is there some sort of update to rules I need to perform?

The problem goes away when I go back down to Shipping 1

This issue is standing in our way of working with Tim Rohaly on the Fed Ex Commerce module, so the quicker we fix this, the quicker he can get his code out to the community.

Thanks for any help
The 7.x-2 branch of Commerce Shipping is only in beta, it's not ready for production use yet (but you probably already know that). 

The release notes for the branch warn you not to install this on a site that currently uses v1.x of the shipping module:


  Note: If you are currently using Shipping 1.x on a live site, do not attempt an update on your live site. See the roadmap below for more information.


(emphasis theirs, not mine!)

I would heed that warning if I were you :)
