I am also getting the message
"Can't locate object method connect via package DBI at ..."
My OS is Red Hat Linux 5.3 and the context is installation of Koha library software. I get the same error in two different places: trying to connect to Koha and trying to run zebraqueue_daemon.pl.
I am certain that DBI is installed, and both DBI directory and DBI.pm are in my @INC path, and that the perl code includes the statement 'use DBI'.
(I did have to do a 'force install' on Bundle:

BI from cpan.)
I have written a very simple script with a dbi->connect command and get the same error.
If anybody could post a solution for this, I would be most appreciative.
