and you upgraded some of the perl... methinks.

This is a symptom caused by loading a compiled CPAN library which is
older than the current perl. The problem is that none of the DXSpider
modules qualify because none of them have a compiled ('XS' as in
'XSLoader') portion. They are all pure perl and cannot cause this error
themselves. 

Having said that: modules/libraries that these modules call - *could*
cause this. The candidates for the highest module in the traceback
(Prefix.pm) are:

IO::File
Data::Dumper
DB_File

As far as I know, both IO::File and Data::Dumper as part of the 5.8.x
perl distribution and DB_File tends to be separate. I would do a check
to see if there is a later update for DB_File as an RPM, otherwise I
would configure CPAN (perl -MCPAN -e shell) and "install DB_File". For
starters...
