Comment(by rgommers):

 This works with my local checkout and doing "pip install -e .". In that
 way {{{--egg-base}}} is not in sys.argv though. How did you test that?

 Can you also explain what these lines do?
 {{{
         if '--egg-base' in sys.argv:
             idx = sys.argv.index('--egg-base')
             sys.argv[idx + 1] = os.path.join(local_path, 'pip-egg-info')
 }}}

 I also didn't find a reliable way to detect whether the install is being
 driven by pip unfortunately.
