Hi Alan. The code in the traceback is being done internally. my code
has "import sqlite3". Python finds it in this directory:

/usr/local/lib/python3.3/sqlite3/

and runs the code from the traceback. I have no idea why it's using _sqlite3:(

Hi, Danny & Kushal.
Originally i only had python 2.7 and 3.2 as default for Ubuntu. Kushal
you're right my 3.2 has a different path to sqlite3 than

/usr/local/lib/python3.3/sqlite3/

Infact i haven't been able to find its location. 3.2 imports sqlite3
with no errors. I'm currently not on ubuntu to try your instruction.
Will the build logs be inside the python3.3 directory? I'm still new
to linux so sorry for newbie questions. it took me a very long time to
get it right when building python3.3. When you say rebuild, is there a
command for doing that or do you mean simply uninstall python then
build it again?
