b2 is not caching anything.  The problem is that both
possible link targets exist in your directory structure.

Possible causes:
- You didn't update parameter after adding parameter_python.
- You are on a branch which does not yet have parameter_python,
  but the library was not removed when you switched to that branch.
- You checked out a revision of the superproject which is in
  an inconsistent state.  (because changes that span repositories
  are not atomic).
