i had the exaxt same problem and the solution was to initialize the proxy before sending the request

perldoc lwpcook gives some hints on this :

PROXIES 
    Some sites use proxies to go through fire wall machines, or just a
+s cache in order to improve performance. Proxies can also be used for
+ accessing resources through protocols not supported directly (or sup
+ported badly :-) by the libwww-perl library.

    You should initialize your proxy setting before you start sending 
+requests: 

      use LWP::UserAgent;
      $ua = LWP::UserAgent->new;
      $ua->env_proxy; # initialize from environment variables 
      # or
      $ua->proxy(ftp  => 'http://proxy.myorg.com');
      $ua->proxy(wais => 'http://proxy.myorg.com');
      $ua->no_proxy(qw(no se fi));

      my $req = HTTP::Request->new(GET => 'wais://xxx.com/');
      print $ua->request($req)->as_string;

    The LWP::Simple interface will call env_proxy() for you automatica
+lly.
    Applications that use the $ua->env_proxy() method will normally no
+t use the $ua->proxy() and $ua->no_proxy() methods.

    Some proxies also require that you send it a username/password in 
+order to let requests through. You should be able to add the required
+ header, with something like this:

     use LWP::UserAgent;

     $ua = LWP::UserAgent->new;
     $ua->proxy(['http', 'ftp'] => 'http://username:password@proxy.myo
+rg.com');

     $req = HTTP::Request->new('GET',"http://www.perl.com");

     $res = $ua->request($req);
     print $res->decoded_content if $res->is_success;
