If I comment out the "self.clean_stale_files()" line from src/setup.py,
then I still get an error, but one you might expect from Python3:
"NameError: name 'unicode' is not defined". This comes from
src/sage/misc/sageinspect.py:
if not isinstance(r, string_types):
return ''
elif isinstance(r, unicode):
return r.encode('utf-8', 'ignore')
else:
return r
