Error while install via composer

[Atorich]

Part of require-dev:

...
"components/ember": "dev-master",
"components/ember-data": "dev-master"
...

Result is:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for components/ember-data dev-master -> satisfiable by components/ember-data[dev-master].
    - components/ember-data dev-master requires components/ember 1.* -> no matching package found.

If we change ember's version to 1.*@dev installation will be successfully but with ember 1.4.0.
