pyinstaller not working with multiprocessing.Manager()

[spongebob]

I'm trying to build a standalone .exe using python's multiprocessing.Manager with pyinstaller but I get the following error:

Process SyncManager-1:
Traceback (most recent call last):
  File "c:\trunk-r767\trunk\manager_test\build\pyi.win32\manager_test\outPYZ1.py
z/multiprocessing.process", line 232, in _bootstrap

  File "c:\trunk-r767\trunk\manager_test\build\pyi.win32\manager_test\outPYZ1.py

  File "c:\trunk-r767\trunk\manager_test\build\pyi.win32\manager_test\outPYZ1.py
z/multiprocessing.managers", line 499, in start
EOFError

If i build to a directory instead of a standalone package, it runs fine.

configuration:

latest svn of pyinstaller

activepython 2.6.4.8

test script to reproduce error:

import multiprocessing

if __name__ == '__main__':

    multiprocessing.freeze_support()

    man=multiprocessing.Manager()

Question: Can you suggest a workaround/solution?
