#unmet_dependencies ⇒ Object

Identify and mark unmet dependencies. A dependency will be marked unmet for the following reasons:

* installed and does not meet the version requirements for this module
* installed and doesn't use semantic versioning

Returns a list of hashes representing the details of an unmet dependency.

Example:

[
  {
    :reason => :missing,
    :name   => 'puppetlabs-mysql',
    :version_constraint => 'v0.0.1',
    :mod_details => {
