Minimal example to reproduce pyinstaller issue #1105

Problem with conflicting .so files pyinstaller/pyinstaller#1105

To reproduce:

1. Download the gist

2. Gist doesn't support directories, so manually create the submodule:

   $ mkdir submodule
   $ mv __init__.py _random.pyx submodule/
   

3. Use cython to compile the .so:

   $ python setup.py build_ext --inplace
   

4. Run normally, it works:

   $ python pyi_so_conflict.py
   success!
   

5. Run through pyinstaller --onedir, it works:

   $ pyinstaller --onedir --name=onedir pyi_so_conflict.py
   [...]
   $ dist/onedir/onedir
   success!
   

6. Run through pyinstaller --onefile, it fails:

   $ pyinstaller --onefile --name=onefile pyi_so_conflict.py
   [...]
   $ dist/onefile
   Traceback (most recent call last):
     File "<string>", line 2, in <module>
     File "/usr/local/lib/python2.7/site-packages/PyInstaller/loader/pyi_importers.py", line 270, in load_module

     File "/Users/ronen/test/pyi_so_conflict/build/onefile/out00-PYZ.pyz/submodule", line 1, in <module>
