IIRC, pysqlite was a wrapper for the SQLite library. However, in
version 2.5+ of Python, it's part of the standard distribution and is
in the module called sqlite3. Just walking throuh the instructions
(although I only have 2.5.2 installed gives me this):

Python 2.5.2 (r252:60911, Oct  5 2008, 19:24:49)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
>>> import pysqlite2


Are you trying to set up using 2.4 or 2.5? I'm just a little confused
as to why if sqlite works on 2.4 which looking at the installation
instruction [ref: http://www.installationwiki.org/Installing_Trac_and_Subversion#Python]
is what's recommended, is what the problem is?

As you're under a redhat derivative, perhaps it might be worth just
getting the rpm(s) for pysqlite2 and that might well sort it out for
you.

Sorry to have not been of more help,

Jon.
