Thank you!  While I'm certainly not down to the bottom of this mystery,
I have a few clues.  First, the important point to make for original
questioner mark is that SQLite(3) is a perfectly reasonable implementation
to use in a Python2.5 context.

I now suspect that my 2.5 packaging has something to do with 64-bit builds;
all my 32-bit Ubuntu servers have Python 2.5.2, while the 64-bit ones are at
Python 2.5.
