Compilation error on Perl 5.8.0

At my workplace, we tried upgrading to the new version of Perl 5.8.0,
but it broke some jobs(wk_job.sh that in turn calls Perl scirpts to
Connect to Oracle 9i) that were running fine in the previous version
(5.6.1). I am not sure what to do. The platform is HP-UX and when I run
my script I receive the errors -

Can't find 'boot_DBI' symbol in

The contents of my @INC variable is -
/opt/perl/lib/5.8.0/PA-RISC1.1-thread-multi
/opt/perl/lib/5.8.0
/opt/perl/lib/site_perl/5.8.0/PA-RISC1.1-thread-multi
/opt/perl/lib/site_perl/5.8.0
/opt/perl/lib/site_perl

and one of them contains the Oraperl.pm module. I am not sure what the
problem is. How are Oraperl.pm and DBI.pm related? Is this error
because one of them is not properly installed?

Any tipcs would be greatly appreciated.
