Have a look at the embperl log and/or the apache error log, there
should be a line similar to the following:

Can't locate in @INC (@INC contains: <list of dirs>)

This list of directories is where embperl/perl is looking for your
module. In order to fix this you'll need to tell the webserver
environment where else to look for modules outside the normal system

I'd recommend creating a file and placing all perl
directives in there for Apache to run.

The line:


in your httpd.conf will tell mod_perl to execute from the
apache config root (eg /etc/apache)

Heres a quick example Its cut down from our real one but
it should be enough for your purposes. Comment out modules that you're
not using.

#! /usr/bin/perl
# mod_perl init

# $Id:,v 1.33 2001/11/16 04:09:51 andrewo Exp andrewo $

# add paths for local modules
use lib qw(

# load frequently used modules in the parent

#use Apache::DBI; # load Apache::DBI before DBI!
use DBI;
use DBD::Pg; # or whatever DBD module you're using (if any)

use Apache::Session; # load Apache::Session before Embperl!
use HTML::Embperl;
use HTML::EmbperlObject;

use ConnectDB;

# kill -USR1 <spinning httpd PID> for perl stacktrace
use Carp ();
$SIG{'USR2'} = sub {
  Carp::confess("caught SIGUSR2!");
