无法找到Module Apache :: DB的可加载对象

Question

我是Perl的新手。我正在尝试根据此（http://docs.activestate.com/komodo/4.4/debugperl.html）在Komodo IDE中设置Apache Debugger。但是，重新启动httpd时（在CentOS中）我收到以下错误消息：

Apache / DB模块确实存在于/opt/perl-5.22.0/lib/site_perl/5.22.0中。请看下面的截图：

Httpd config：

<Perl>
  use ModPerl::Registry;
  use lib qw(/media/sf_perllib);
  $ENV{PERLDB_OPTS} = "RemotePort=192.168.0.38:12346 LogFile=stderr";
  use Apache::DB ();
  Apache::DB->init;
</Perl>
