undefined method `from_gemfile' for Bundler::Definition:Class

[r3ap3r2004]

The latest version of Bundler 1.0.0.rc.4 doesn't appear to have a from_gemfile method.

This is being called from the my_engine/engine.rb file inside the my_engine.require_dependencies initializer.

Not being the bundler expert I'm not really sure how to solve the problem, but the engineer "rails g my_engine:install" method from inside the host does not work without it.

As a work around, you can comment out that initializer, and instead maintain your list of dependencies within the gemspec block inside your Rakefile (a la jeweler.)

I know maintaining two lists is annoying, but it should get you by while I take a look.

That's actually what I did. I'm now having another issue that I can't seem to figure out.
See:
http://github.com/phs/engineer/issues/issue/2

When I start the host application and visit a route in my engine the stylesheet and javascript links that get created inside the engine all have the appropriate ASSET_PREFIX appended to them like they should and everything works great.

But, when I reload the page (without restarting the server) any subsequent page view is missing the ASSET_PREFIX which of course causes all the necessary javascript and stylesheets to look in /javascripts, etc instead of /my_engine/javascripts like it should.

I am running rails 3.0.0-rc (although I have also tried with the latest rails master code with the same results).

Any insight into how to fix this would be greatly appreciated.
