Error, Undefined symbol "PyGILState_Ensure"

Hello All, 

I would like to use pysqlite2 on rental FreeBSD(4.10-RELEASE-p16)
Server. And I have no privilege on that server. Sqlite and
pysqlite was not provided on the server, so I installed them
under my home directory. It seems sqlite works properly. But when
I run pysqlite I got this error:

Python 2.4.2 (#2, Nov 14 2005, 12:00:29)
[GCC 2.95.4 20020320 [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information.
>>> from pysqlite2 import dbapi2 as sqlite
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/home/my-account/usr/lib/python/pysqlite2/dbapi2.py", line 27, in ?
    from pysqlite2._sqlite import *
ImportError: /home/my-account/usr/lib/python/pysqlite2/_sqlite.so: Undefined 
symbol "PyGILState_Ensure"
>>>

What does mean this error? and how do I correct this error?
If you need other information, please ask.

thanks.
