Have you tried using the latest BerkeleyDB with an in-memory only database? It may be fast enough and small enough for your needs. If that doesn't work, you could consider using a C hash library and writing a thin Perl front-end to it (maybe with Inline::C), which would give you total control of the tradeoff in speed vs. memory for your application.
