pysqlite is included in the standard library in Python 2.5, that is why
there is no support on the pysqlite web site.
The package name is different, you can write the code with conditional
import sqlite3 as sqlite # Python 2.5
from pysqlite2 import dbapi2 as sqlite
If changing the code is not an option you might be able to fake it out
by making a pysqlite2.dbapi2 module that just contains
from sqlite3 import *
I haven't tried any of this so I could be off base. I'm assuming that
the bundled version is the same as the one you have at work other than
the package name
You don't say what OS you are running but under Windows it is trivial to
have multiple versions of Python installed, I have 2.3, 2.4 and 2.5.
They are each in their own directories, all in the system path. I have
aliases called py23, py24 and py25 that let me launch the version I
want. I'm pretty sure you can do something similar with other OSes.
