It looks like you have an incomplete installation of DBI.  You need
the mysql bindings, and you also need the DBD interface to wrap it, so
technically you need three components.  The various DBD's are often
times installed automagically for you by the DBI installation or by
the port (if you use FreeBSD), however you can't always assume that.
Once you get that fixed, I think you'll be all good to go.  -sc
