rubygems - uninitialized constant Rake::DSL in Ruby Gem

Question

I have been working on updating my gem (whm_xml at https://github.com/ivanoats/whm_xml_api_ruby ) to make it work with ruby 1.9.2, latest rubygems, latest bundler, latest rdoc, latest rake. It works fine in 1.8.7 but has the "uninitialized constant Rake::DSL" error only in 1.9.2 . I thought that rake 0.9.2 fixed that but maybe not? I have read a lot on StackOverflow but am still stuck. Any ideas on where to look?

This SO Question might help you out. The suggestion there is to add require 'rake/dsl_definition' above require 'rake' in your Rakefile.
