vim74 with PyExc_OSError when importing python3 module‏

I have compile vim with python3 support. But when I type "vim -c 'python3 import logging'" in the bash,the vim can't execute the command correctly.

Error detected while processing command line: Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python3.4/logging/init.py", line 26, in import sys, os, time, io, traceback, warnings, weakref, collections ImportError: /usr/local/lib/python3.4/lib-dynload/time.cpython-34m.so: undefined symbol: PyExc_OSError

I don't know the reason.
