Incompatible versions: rails, haml_coffee_assets and tilt.

[ptrhvns]

I think the gemspec for haml_coffee_assets may have too broad a spec for tilt:

# ...
s.add_runtime_dependency 'tilt', '>= 1.3.3'
# ...

That spec, combined with the fact that the tilt gem just upgraded to 2.0.0 on November 30th, is leading to this problem with Rails:

# ...
Bundler could not find compatible versions for gem "tilt":
  In Gemfile:
    rails (= 3.2.15) ruby depends on
      tilt (!= 1.3.0, ~> 1.1) ruby

    haml_coffee_assets (~> 1.15.1) ruby depends on
      tilt (2.0.0)
# ...

I was able to resolve the issue by putting a tilt spec in my Gemfile:

gem 'tilt', '~> 1.4.1'

And I confirm the workaround by specifying tilt version directly in my Gemfile.

Rails : 3.2.13
Ruby : 2.0.0p353

Thanks for reporting. Version 1.16.0 should fix this issue.
