我现在正在Ubuntu 16.04上实现net-snmp代理，通过引用此站点（https://kadionik.vvv.enseirb-matmeca.fr/embedded/snmp/english/net-snmp_english.html）
但我在“4.2 NET-SNMP代理扩展”处停了下来
当我执行'perlMakefile.pl'时，会显示以下错误消息。（perl版本：第5.22.1节）
在MakefileSubs.pm@INC中找不到www.example.com（您可能需要安装MakefileSubs模块）（@INC包含：/etc/usr/local/lib/site_perl /usr/lib/arm-linux-gnueabihf/perl-base .）在生成文件的PL第7行。开始失败--编译在生成文件处中止。PL线7。
下面是Perl脚本。

use Cwd 'abs_path';

WriteMakefile(DefaultStoreInitMakeParams());

    my $opts;
    my %Params = (
      'NAME'        => 'NetSNMP::default_store',
      'VERSION_FROM'    => 'default_store.pm', # finds $VERSION
      'XSPROTOARG'          => '-prototypes',
      );

AddCommonParams(\%Params);

if ($Config{'osname'} eq 'MSWin32' && !defined($ENV{'OSTYPE'})) {

我已经检查了许多建议来解决这个问题，并安装了一些包，'libsnmp-perl'，'libnet-snmp-perl'.
但我至今还没有洗清这个问题。
