Exception starting freshly installed web2py on Linux

Question

After uncompressing web2py latest source on Linux Redhat 64bit (Python 2.7.3), I start the server and the first call generates this stack trace:

Anyone can help please?
Thanks

Learn to format your code on here (format the exception as code). We'll likely need to some code too. — Marcin, Nov 13 '12 at 19:10
Yep, did that on the third try :) I have no code to show, this is web2py out-of-the-box. — friol, Nov 13 '12 at 19:11
Possible duplicate of: [Why does web2py crash for me upon startup?](http://stackoverflow.com/questions/8857953/why-does-web2py-crash-for-me-upon-startup). I seems to be that it can't find any database driver package installed. Which database backend do you plan to use? SQLite at least should be available though (that comes with the Python standard library). See also: [web2py manual: The database abstraction layer](https://web2py.com/books/default/chapter/29/06). — Pedro Romano, Nov 13 '12 at 20:01
I'm aware of that question, but it didn't answer mine... Now I'm investigating because in my installation of python (I didn't do it), sqlite3 seems to be missing (import sqlite3 gives an exception). — friol, Nov 13 '12 at 20:24
The fact that your Python installation doesn't have the `sqlite3` package is indeed abnormal, and that would explain the error. In my Ubuntu installation it is definitely part of the base `python-2.7` package. — Pedro Romano, Nov 13 '12 at 20:37
Seems that the sysadmins recompiled python from source in order to install it, but didn't include the sqlite3 library... I still have to get an official feedback. — friol, Nov 14 '12 at 19:05

This issue was related to sqlite3 missing from Python's installation.

Recompiling Python with that library fixed the problem.
