sqlite3 and Python 2.5.1

[milan_sanremo]

I have sqlite installed, but when I try to import sqlite3 I receive:

Python 2.5.1 (r251:54863, Nov  3 2007, 02:54:36) [C] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named sqlite3
>>>

Yet:

# find /usr/local/python -name "sqlite*" -print
/usr/local/python/lib/python2.5/sqlite3

# /opt/csw/bin/sqlite3
SQLite version 3.2.2
Enter ".help" for instructions
sqlite>

What is missing?
