As roundabout and advanced as that code is, it doesn't give the right 
answer for me.  It returns None.  On my Mac, after activating a virtualenv:

     Python 2.7.2 (default, Oct 11 2012, 20:14:37)
     [GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] 
on darwin
     Type "help", "copyright", "credits" or "license" for more information.
     >>> from distutils.command.install import install
     >>> from distutils.dist import Distribution
     >>> c = install(Distribution())
     >>> c.install_scripts
     >>> c.install_scripts is None
     True
     >>> sys.executable
     '/usr/local/virtualenvs/studygroup/bin/python'
     >>> os.listdir(os.path.dirname(sys.executable))
     ['activate', 'activate.csh', 'activate.fish', 'activate_this.py', 
'easy_install', 'easy_install-2.7', 'pip', 'pip-2.7', 'python', 
'python2', 'python2.7']
     >>>
