dear monks, im very new to perl and im having problems with a module. my comptuer is behind a firewall and i dont know how to work this problem out. i tried passing my proxy parameters (ip, port, user, pass) to my environment variables but it doesnt seem to work. heres the almost exact code from the module manual:

use Mail::Client::Yahoo;
my $y = Mail::Client::Yahoo->login(
           username => 'user',
           password => 'passwd',
           secure   => 0,                                      );
$y->select_folder('Inbox');
print $y;
my $m = $y->message(0);        
print $m;
my  @ids = $y->message_list();
print @ids;
$y->message($ids[0]);
print $y;
# $y->delete_message(0);
$y->logout();

the error i keep on getting is: Login failed on Front Page Retrieval: Proxy Authentication Required at /usr/lib/perl5/site_perl/5.8.6/Mail/Client/Yahoo.pmline 134.
