configurar doctrine2

ola pessoal

estou tentando configurar o doctrine no projeto nao estou conseguindo com o comando

php composer.phar require doctrine/doctrine-orm-module:dev-master

esta aparecendo o erro:

./composer.json has been updated
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 doctrine/doctrine-orm-module dev-master -> satisfiable by doctrine/doctrine-orm-module[dev-master].
- doctrine/doctrine-orm-module dev-master requires doctrine/doctrine-module 0.9.* -> no matching package found.

Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

Read <http://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

Installation failed, reverting ./composer.json to its original content.
