I have a situation in puppet where I want to inherit from a parametrized class:

class base ($basepath) {
  ...
}

class extends_base ($ext_param) inherits base {
  ...
}

Now trying to instantiate the extends_base class I get the following error message:

Must pass basepath to Class[Base]

However, I don't see a way how to pass the basepath parameter to the Base class.. I tried to pass the param in the Class[Extends_base] definition, puppet doesn't like this either.
