how bizarre.
Works here for me 2.3.2

C:\ruby19\bin>irb
>> require 'activerecord'
=> true
>> RUBY_DESCRIPTION
=> "ruby 1.9.1p129 (2009-05-12 revision 23412) [i386-mingw32]"

I think I may have run into something like that once where I was going 
from one rails version to the next--do "fresh" rails apps do that?  Do 
you have other gem versions of rails installed, or in /vendor? There 
might be a conflict.
Cheers!
