Can't bundle when deploying RoR app with passenger

Question

I'm deploying an app to production using passenger and apache. I've deployed multiple apps on the same server without problems. However, for some reason I'm having problems with this app.

When I run bundle I get a lot of warnings I've never seen before:

WARNING:  #<ArgumentError: Illformed requirement ["#<YAML::Syck::DefaultKey:0x7fcbdc2ce610> 1.6.0"]>
# -*- encoding: utf-8 -*-

  s.name = %q{bson_ext}
  s.version = "1.6.0"

  s.required_rubygems_version = Gem::Requirement.new(">= 0") if s.respond_to? :required_rubygems_version=

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Although it appears as if my gems get bundled when I go to my app I get a passenger error.

Anyone have any idea what might be going on?

Thanks in advance.

Apparently its a bug with the ruby mongo driver 1.6.0 working with older RubyGems version. Its already fixed and will be in 1.6.1 (that should have been released a few days ago and i guess will be any day now).

In the meantime, patch your GemFile (hopefully you don't have all that 1.6.0 cherries...):

gem 'bson',  '< 1.6.0'
gem 'bson_ext', '< 1.6.0'
gem 'mongo',  '< 1.6.0'
