Setup environment:

mkdir /tmp/test-offloc-router-silex-app
cd /tmp/test-offloc-router-silex-app
curl https://raw.github.com/gist/a91db56328402b1468f5/a24d920974134fde2484d700c9e17294ac8c50d7/composer.json > composer.json
curl http://getcomposer.org/composer-new.phar > composer-new.phar

Try installing with --dev with new Composer build, fails:

# This breaks!
php composer-new.phar install --dev

...
Installing dev dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for ext-pdo_sqlite == 1.0.1.0 -> satisfiable by ext-pdo_sqlite 1.0.1.
    - ext-pdo_sqlite 1.0.1 requires doctrine/common master-dev -> no matching package found.
  Problem 2
    - Installation request for ext-sqlite3 == 0.7.0.0-dev -> satisfiable by ext-sqlite3 0.7-dev.
    - ext-sqlite3 0.7-dev requires doctrine/common master-dev -> no matching package found.
  Problem 3
    - Installation request for ext-xml == 0.0.0.0 -> satisfiable by ext-xml 0.
    - Can only install one of: ext-xmlreader 0.1, ext-xml 0.
    - Installation request for ext-xmlreader == 0.1.0.0 -> satisfiable by ext-xmlreader 0.1.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

Try updating with --dev with new Composer build, fails:

Install using default composer, should work? :)

rm -rf composer.lock vendor/

# Fallback to regular composer
composer install --dev
