Martin Fowler's Runt library is really handy for date/time comparisons, and this code works great in an irb console:
require 'runt'
include Runt
r_start = PDate.month(2010,12)
r_end = PDate.month(2011,12)
range = DateRange.new(r_start,r_end)
o_start = PDate.month(2010,11)
o_end = PDate.month(2012,2)
o_range = DateRange.new(o_start,o_end)
range.overlap?(o_range)
but if I add the Runt gem to my Rails 2.3.5 app and try to run the same commands in script/console, I get this error:
NoMethodError: undefined method
`to_datetime' for Mon, 01 Nov 2010

Has anyone encountered this error before, or does anyone know how to begin debugging this? I've tried looking at the spaceship operator in the ActiveSupport calculations module, but I can't figure out how to pick apart the problem.
Thanks very much for your help,
Jacob
