求教：python中datetime.so无法load a runtime definition of the symbol was not found

一个简单的 import time ，但是报错如下
ImportError: rtld: 0712-001 Symbol PyArg_ParseTupleAndKeywords was referenced
  from module /xx/tools/runtime/lib/python2.3/lib-dynload/datetime.so(), but a runtime definition
  of the symbol was not found.
rtld: 0712-001 Symbol PyDict_Size was referenced
  from module /xx/tools/runtime/lib/python2.3/lib-dynload/datetime.so(), but a runtime definition
  of the symbol was not found.
rtld: 0712-001 Symbol PyErr_ExceptionMatches was referenced
  from module /xx/tools/runtime/lib/python2.3/lib-dynload/datetime.so(), but a runtime definition
  of the symbol was not found.

环境变量和配置都检查过了，不明白是什么，求教各位高手
