You've created a class accessor above -- that 'class << self...end'
syntax is modifying the class, rather than instances, so you've made
'defpath' and 'srcpath' class attributes.
However, your self.defpath call is using an instance attribute, since
'enabled?' is an instance method.
Just change this to 'self.class.defpath'. You wouldn't normally need
the 'self', but you can't lead a statement with 'class' because it
confuses Ruby's parser (since 'class' is a reserved word).

Provider, or resource?
You'd access resource attributes like: status = resource[:hasstatus].
Note that versions prior to, I think, 0.24.4 required you to use
'resource.should(:property)' for properties. and 'resource[:param]'
for parameters, for backward compatbility. This has been fixed now,
thankfully, and the [] syntax works everywhere.
