This is what I have:

$VERSION = '3.4.1';
$CORE_CONFIG_FILE = "/etc/request-tracker3.4/RT_Config.pm";
$SITE_CONFIG_FILE = "/etc/request-tracker3.4/RT_SiteConfig.pm";

$BasePath = '/usr/share/request-tracker3.4';

and later on after the =cut:

     if ($RT_INSTANCE_PATH) {
         foreach my $vref (@variables) {
             $$vref =~ s/^\Q$BasePath\E/$RT_INSTANCE_PATH/;
     foreach my $vref (@variables) {
         $$vref = $args{$vref} if defined ( $args{$vref} );

use strict 'refs';

Yeah... this is the core problem.

I'm not very good with Perl, so if you can suggest some debugging 
methods I'll try to use them.
