Builtins module missing?

When I run some scripts I got this errors, is this a problem with my setup?
(I can confirm that my system has the module builtins installed)

Traceback (most recent call last):
  File "New Tab with Transformed Components.py", line 4, in <module>
    from builtins import str
ImportError: No module named builtins

>>> from builtins import str

This is fixed in the script already. Please make sure you update to the latest version.
