1、perldoc perllocal
2、推荐pmtools里的pminst命令
3、编写如下标本
#!/usr/bin/perl
use ExtUtils::Installed;
my $inst = ExtUtils::Installed->new();
print join "\n", $inst->modules();
4、Most of them will probably already be available in your installation. You can check version numbers with the
configure script, or if you're still trying to get to that point, check from the command line like this:
perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'转自:http://blog.chinaunix.net/space.php?uid=20388294&do=blog&id=1690602
