i have solved this problem by install from latest source package. but,
another issue raised, when i called con.execute("select
load_extension('./fts3.so')") and con.execute("CREATE VIRTUAL TABLE
posts using FTS3(title, body);"). the error message is,

>>> from pysqlite2 import dbapi2 as sqlite3
>>> con = sqlite3.connect(":memory:")
>>> con.enable_load_extension(True)
>>> con.execute("select load_extension('./fts3.so')")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pysqlite2.dbapi2.OperationalError: extension loading is disabled

i checked whole file system for fts.so. but there is no fts3.so
anymore. then i downloaded the full source code of latest sqlite, and
compiled it. but also, no fts2.so exists under build folder. finally,
i downloaded sqlite-amalgamation-3_6_4.zip and compiled it with
CFLAGS="-DSQLITE_ENABLE_FTS3=1" option. the whole command line is
"CFLAGS="-DSQLITE_ENABLE_FTS3=1" ./configure". unfortunately, the
fts3.so cannot be found too.
how can i get the fts2.so!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
