Hi!
I'm afraid this was mostly my fault, we released a version of mcollective without some needed metadata and recently changes made this more problematic than it used to be. I've uploaded a new release so you should be able to fix this with:
puppet module uninstall puppetlabs-mcollective
puppet module install puppetlabs-mcollective
If the uninstall step doesn't work, just rm -rf /etc/puppetlabs/puppet/modules/mcollective altogether to force the issue. After this is done you should have v1.1.3 and things should work better!
