bundle install error activeadmin ransack

Question

Am trying to install my own project onto a secondary computer - both are macosx 10.8.4, both setup using macports and RVM.

For some reason as I'm trying to bundle install I'm getting this error:

```

Bundler could not find compatible versions for gem "ransack": In Gemfile: activeadmin (>= 0) ruby depends on ransack (>= 1.0.0) ruby

ransack (0.7.3)

Bundler could not find compatible versions for gem "actionpack": In Gemfile: ransack (>= 0) ruby depends on actionpack (>= 4.0.0) ruby

sass-rails (~> 4.0.0) ruby depends on
  actionpack (4.0.0.beta1)

```

Not sure why bundle install works fine on one computer and not the other; I recently participated in this ransack issue on with activeadmin on github and it seemed to be fixed; unsure why it's popping up again.

UPDATE: gem file:

I think you don't want to use the rails-4 branch of ransack. It looks like the current master version supports Rails 4.

The dependency on the rails4 branch of activeadmin says that it needs ransack >= 1.0.0, but the version of ransack on the rails-4 branch is 0.7.3.

It is probably a better idea to use the released versions of gems from Rubygems unless you need specific unreleased fixes in the Git repo.
