OSError: [Errno 13] Permission denied

[Johnny Bravo]

Hello, this library is just what I was looking for, but I can't get it to host a ftp server as an unprivileged user. I followed the example in "basic_ftpd.py" file but it won't run, it outputs:

./ftpserver.py

Traceback (most recent call last):

  File "./ftpserver.py", line 12, in <module>

    from pyftpdlib.servers import FTPServer

  File "/usr/lib/python2.7/site-packages/pyftpdlib/servers.py", line 529, in <module>

    class MultiprocessFTPServer(_SpawnerBase):

  File "/usr/lib/python2.7/site-packages/pyftpdlib/servers.py", line 533, in MultiprocessFTPServer

    _lock = multiprocessing.Lock()

  File "/usr/lib/python2.7/multiprocessing/__init__.py", line 176, in Lock

    return Lock()

  File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 147, in __init__

    SemLock.__init__(self, SEMAPHORE, 1, 1)

  File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 75, in __init__

    sl = self._semlock = _multiprocessing.SemLock(kind, value, maxvalue)
OSError: [Errno 13] Permission denied

I have tried using the older approach with pyftpdlib.ftpserver too, with no luck. 

Python 2.7
