DB up to and including 1.86 are Berkeley license (basically 'do anything with this but include this notice' but without open source requirements), but DB up to and including 1.86 only allow < 2GB databases. :-( I tried to upgrade it with 64-bit integers, but it's such convoluted C code I can't make head nor tail of it. Also try buying BDB ($20,000). I emailed them asking for a discount, but Oracle (who owns them now) never replied. :-(
