[error] Can't load Perl module DBI for server localhost:80, exiting...

Hi,
I get the following error when I put in httpd.conf:

PerlModule DBI

and in error.log:
[Fri Nov 26 18:50:52 2004] [error] Can't load Perl module DBI for
server localhost:80, exiting...

I have DBI 1.45, Apache 2.052 Win32, mod_perl 1.99_17, Perl 5.84. I am
very sure that @INC contains the right path, and simple DBI stuff can
run on the command-line.

Any comments are highly appreciated.
