[PyCuda] Strange warning when launching test_driver.py

[Hua Wong]

It says "OK" at the end, so I should be golden (¿o rly?)

I just would like to know what is the warning about (maybe it's 
something I can correct) something about sqlite?
What does it do?

python test_driver.py
/work/hwong/site-packages/lib64/python2.4/site-packages/pytools-9-py2.4.egg/pytools/diskdict.py:119: 
UserWarning: DiskDict will memory-only: a usable version of sqlite was 
not found.
