LWP::UserAgent Protocol scheme 'http' is not supported

当我运行下面的脚本的时候，报错“Protocol scheme 'http' is not supported,_rc==>501”.

##!/bin/sh

# Source needed files

. /home/citminst/sqllib/db2profile

exec /opt/freeware/bin/perl5.8.8 -x $0 $@

#!perl
#line 9

use strict;
use LWP;
use URI::Escape;

 my $uid='test@cn.ibm.com';
 my $browser = LWP::UserAgent->new;
 my $response = $browser->get("http://bluepages.ibm.com/BpHttpApisv3/wsapi?byInternetAddr=" . uri_escape($uid));


 while ( my ($key,$value) = each %$response ) {
           print "$key => $value\n";
 }

 if ( $response->is_success ) {
	print "--------success\n";
 }else {
	print"-------failed\n";
 }

经过测试发现原来缺少安装Net::HTTP module.因为LWP::UserAgent 需要Net::HTTP.
