gem dependency version conflicts between a gem's spec, bundler, and gem install

I'm trying to install a gem, meta_search-1.1.0.pre2. The gem's spec, bundler, and rubygems each report/install different dependency version requirements.

I have a new rails3 project (here are my rails, ruby, rubygems and installed gem versions), with one new line in my Gemfile:

gem 'meta_search', '1.1.0.pre2'

meta_search's page on rubygems.org reports these dependencies:

actionpack ~> 3.1.0.alpha
activerecord ~> 3.1.0.alpha
activesupport ~> 3.1.0.alpha

However, installing it pulls down activesupport and activemodel-3.1.1.rc1:

 Successfully installed meta_search-1.1.0.pre2

 3 gems installed

..and bundler reports that meta_search needs activesupport-3.1.0.beta1.

muldoon@fedora14$ bundle update

Bundler could not find compatible versions for gem "activesupport":
  In Gemfile:
    rails (= 3.1.0) depends on
      activesupport (= 3.1.0)

    meta_search (= 1.1.0.pre2) depends on
      activesupport (3.1.0.beta1)

Very strange! Any suggestions?

thx! Mike

If you're using rails 3.1.0, you should be using meta_search 1.1.0, like this:

gem 'meta_search', '1.1.0'

When you run bundle install, do you get any errors? Bundler should solve any dependency issues for you with this command.

When you run bundle update, it searches for the latest version of every gem.
