I think that the issue is that the define isn't actually scoped under
the class, so the inherit doesn't pick up that the file is actually
under that class at all. Does that make sense?
Try writing the same statement but move the defines outside of the
classes and I think you'll see exactly what I'm talking about.
Basically, you can't inherit defines (I think) because they actually
aren't derived from the Puppet Class object.
I.e. a Node is a subset of a Class, but a Define isn't.
