First off, as you feared, Gadfly seems to be unsupported.  It should
work on Python 2.1, but will generate a couple of warnings due to use
of deprecated modules.

If you only want to search on one or a few fields and don't need
pattern search (like 'get all lines where the 'user' field starts with
a 'd'), a DBM-based solution or a pickled dictionary should be ok.
Otherwise you will need a more sophisticated database, like Postgres
or MySQL, to get good performance.  I haven't used Berkeley DB and I'm
not aware of it's capabilities.  It might be good enough.

Peace,
  Kalle
