There's a little bug in the site module. Have a look at line 95. There
sys.path[-1] is being accessed without being tested first. If you follow
Py_FrozenMain you'll notice that freezed modules may have an empty sys.path,
and it breaks.

You may fix site.py and add a test to verify if sys.path is not an empty
list before accessing its last element (-1), or set sys.path in the
command line using PYTHONPATH environment variable. You may also change
Py_FrozenMain and set sys.path to something like Py_GetPath() there.

Best regards!
