qualify Distribution by module name pkg_resources

[MAKOMO]

The seems to be a typo in recipes/setuptools.py quite for a while which results in

File /Applications/MyApp.app/Contents/Resources/__boot__.py", line 233, in find_eggs_in_zip
  yield Distribution.from_filename(path_item, metadata=metadata)
           ^^^^^^^^^
NameError: name 'Distribution' is not defined

I encountered the same issue in __boot__.py, this bug should be fixed.
