Hello All,

[Fri Aug 20 11:48:41 2010] [error] Can't locate ARS.pm in @INC (@INC contains: /opt/app/ars/ovsc/perl /usr/perl5/5.8.4/lib/sun4-solaris-64int

We have installed apache(Apache/2.2.10) and we have a .pl file that is being loaded in httpd.conf.

When we are trying to restart the server, We receive the following error : 
LoadModule perl_module    modules/mod_perl.so
httpd.conf file : 
<IfModule mod_perl.c>
    PerlRequire "/opt/app/ars/ovsc/perl/startup.pl"

This is our perl file : 

our perl file that apache is trying to load contains this :

use lib qw(/opt/app/ars/ovsc/perl);

use MIME::Base64;
use ARS;
use Unicode::String;
use POSIX;

use Apache2::Const -compile => qw(LOG_DEBUG LOG_INFO);

$ENV{ARCONFIGDIR}="/opt/ars/arserv/0/conf";

$MAIN::OVSC_PATH='/opt/app/ars/ovsc';
$MAIN::UPLOAD_PATH='/opt/app/ars/ovsc/ToWIH';
$MAIN::MBOX="";
 
Please suggest us what needs to be done.
