I believe it's a glitch in the 2.5.1 distribution current on Cygwin - I
had to install the _sqlite DLL separately to get it to work, but no
recompilation was necessary AFAICR.

Chui Tey detailed the necessary steps in his blog post "Cygwin Python
and sqlite3", but sadly it got lost and he hasn't replenished it, so you
will have to stab around to see if there's a cached copy anywhere.
