rfpkg trouble: "ImportError: No module named builtins"

Hi, I haven't used rfpkg for maybe 6 months. Have been using fedpkg with success. I'm trying a number of commands with f29 rfpkg: === rfpkg clone free/audacity-freeworld Traceback (most recent call last): File "/usr/bin/rfpkg", line 11, in <module> load_entry_point('rfpkg==1.26.2', 'console_scripts', 'rfpkg')() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 489, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2793, in load_entry_point return ep.load() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2411, in load return self.resolve() File "/usr/lib/python2.7/site-packages/pkg_resources/__init__.py", line 2417, in resolve module = __import__(self.module_name, fromlist=['__name__'], level=0) File "/usr/lib/python2.7/site-packages/rfpkg/__init__.py", line 18, in <module> import rpmfusion_cert File "/usr/lib/python2.7/site-packages/rpmfusion_cert/__init__.py", line 18, in <module> from builtins import str ImportError: No module named builtins === It might be related to python3 v2, but I'm sure if that was the case I wouldn't be the only one with an issue ?
