`puppetlabs-stdlib` dependency is not recognized (puppet version 3.7.2)

[trueneu]

Puppet 3.7.2 fails to recognize puppetlabs-stdlib dependency:

Warning: Missing dependency 'puppetlabs-stdlib':
  'bfraser-grafana' (v2.0.2) requires 'puppetlabs-stdlib' (>= 3.2.0 <5.0.0)

(the version of bfraser-grafana is certainly not the latest, but if I force upgrade it to the latest, puppet starts to whine about puppetlabs-apt too).
Changing - to / helped me, though I don't know if it affects other puppet versions. (created a PR #102)

I think this has been fixed by voxpupuli#1.
