From POSTER:

So I managed to get in touch with Paul Marquess (a Perl developer) because I pretty much determined this is a bug, and low and behold it is. From his mouth:

You can safely ignore the warning if you want. Otherwise upgrade to the latest version of DB_File - which is version 1.807. FYI, this particular problem was fixed in DB_File version 1.805

The cause for this was the undef in my statement to open the DBASE

Just information in case someone else runs across this problem in the future!
