The Darwin-specific getproxies_internetconfig() was added to urllib, causing test_pyclbr to fail on all other platforms.  Added that routine to the urllib "ignore" list. Removed the special case for "g" in the pickle module.  types.py deletes "g" from its namespace; maybe it didn't always.  Whatever, the special case isn't needed today.
