I had a similar problem uploading a pre-made berkeley DB (created locally using Macperl) to my web site. Same program on both platforms, but I suspect different versions of perl and or DB_File module. I suggest finding someone with this earlier combination and installing it there (maybe your webhost can tell you what the previous version was). My solution was to convert the DB to flat-file, upload it, and then convert to DB_File on the server. Maybe the reverse will work for you? Tod.
