sudo python setup.py install

## 如果上面的libmemcache没打补丁的话, 会出现下面的错误:

>>> import cmemcache
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/cmemcache.py", line 60, in <module>
    from _cmemcache import StringClient
ImportError: /usr/local/lib/libmemcache.so.0: undefined symbol: mcm_buf_len

settings的
