I’ve published a project on github https://github.com/practicalweb/vagrant-rpmbuild

The project contains a Vagrant config file, and Puppet manifests that together with an appropriate basebox will create a VM setup to build RPMS and host them on a Custom Yum repository

To run this

If you want to create custom rpms and install then with the usual automated dependency management you’ll need your own yum repository. This is just the RPMS and metadata in the format of static xml files served by a webserver.

I had a centos VM that I hadn’t used in a while, I think I cloned it from another version.

When I came to use it again I had no network andtrying to start the network I got the error message in the title.

There seem to be a few issues

Drupal has a fairly easy to meet set of requirements http://drupal.org/node/502452

But Drupal projects are free to set their own rules in this area and Drush has used functions only available in PHP 5.2 - as far as I can see this is just the json functions.
