After upgrading to SabreDAV2/VObject3, new packages are required.
Use git master head from rI. This will start the 0.4.x series.
Dependencies are listed in `composer.json` and shall be installed as individual php-* packages (T55).
Use `composer-dist.json` to just build a local autoloader for the iRony project which is configured to load classes from `/usr/share/php/` and `/usr/share/pear/`
