pyinstaller pack zmq error

[friddle]

https://github.com/zeromq/pyzmq/blob/master/zmq/__init__.py

when i use pyinstaller to pack my source and I found this problem.

And I debug I found that

    try:
        from . import libzmq
    except ImportError:
        pass

In pyinstaller,import error when i execute the pyinstaller executable file.
os.getcwd() is to my execute location,not include libzmq.so。
when I change the location to the folder where include libzmq.so..I could not import libzmq.so ethir
when I copy libzmq.so to excutable root folder and import again.
it is ok,but stranger
this is fix code

     try:
        from . import libzmq
    except ImportError as e:
        #for compatiable pyinstaller runner
        import os;os.chdir(os.path.join(os.path.dirname(__file__),"../"))
        import shutil;
        if os.path.exists("./zmq/libzmq.so"): shutil.copy('./zmq/libzmq.so','./');
        import libzmq

please fix this problem.

Is the libzmq.so included in the bundle, just not loaded?
