Dependency hell with version 0.1.4

[egeexyz]

I'm migrating an EmberJS site to Middleman and thought this Gem would help. Attempted to install it against a brand new Middleman template and got this series of dependency errors:

Bundler could not find compatible versions for gem "ember-source":
  In Gemfile:
    emberman (~> 0.1.4) was resolved to 0.1.4, which depends on
      ember-data-source (= 1.0.0.beta.14.1) was resolved to 1.0.0.beta.14.1, which depends on
        ember-source (~> 1.8)

    emberman (~> 0.1.4) was resolved to 0.1.4, which depends on
      ember-source (= 1.10.0.beta.4)

Bundler could not find compatible versions for gem "middleman-core":
  In Gemfile:
    emberman (~> 0.1.4) was resolved to 0.1.4, which depends on
      middleman-core (~> 3.3.7)

    middleman (~> 4.2) was resolved to 4.2.0, which depends on
      middleman-core (= 4.2.0)

My platform is Linux, Fedora 26. The second set of errors for "middleman-core" look strange, but when I remove gem 'emberman', '~> 0.1.4' they go away completely.

@brandon-meeks thanks! Sorry about that, I haven't used this in ages and kind of forgot about it. Will give it a once-over and try to bring it back to life ASAP (or retire it if not worth it.).

BTW, not sure if it applies for what you're trying to accomplish, but have you seen https://github.com/ef4/prember ?
