C. or modify the scripts manually by replacing all the following block

use vars qw($SCRIPT_DIR);

if ( $ENV{'SCRIPT_FILENAME'} =~ m!^(.*?)/[\w\d\-\.]+\.pl! || $0 =~
m!^(.*?)/[\w\d\-\.]+\.pl! ) { $SCRIPT_DIR=$1; }
if (!$SCRIPT_DIR) { print "Content-type: text/html\n\n\ not
set in CGI script!\n"; exit 0; }
push (@INC, $SCRIPT_DIR, ".");

with

use vars qw($SCRIPT_DIR);

if ( $0 =~ m!^(.*?)/[\w\d\-\.]+\.pl! ) { $SCRIPT_DIR=$1; }

if (!$SCRIPT_DIR && open(F, '/etc/openwebmail_path.conf')) {

$_=<F>; close(F); if ( $_=~/^([^\s]*)/) { $SCRIPT_DIR=$1; }

}

if (!$SCRIPT_DIR) { print "Content-type: text/html\n\n\SCRIPT_DIR not set
