It is a bit ugly but here is an initial port of the Shoulda ActiveRecord 
macros:

http://gist.github.com/14050

I did not try running ALL of the macros, but most of them.  Before going 
too far with it, I would appreciate some recommendations as to how to 
improve the flow.  The Shoulda version has a different feel to it since 
the assertions cause the code to die early.  Whereas the RSpec 
conversion I did mostly wrap each should call in its own it block.

Thanks for the help!  I learned a lot from this exercise!
