首先下载最新的perl源码包：
[root@akinlau /]# wget http://www.cpan.org/src/5.0/perl-5.16.1.tar.gz
解压源码包
[root@akinlau /]# tar -xzf perl-5.16.1.tar.gz
编译并安装,目录可以自定义
[root@akinlau /]# cd perl-5.16.1
[root@akinlau perl-5.16.1]#./Configure -des -Dprefix=/usr/local/perl
[root@akinlau perl-5.16.1]# make
[root@akinlau perl-5.16.1]# make test
[root@akinlau perl-5.16.1]# make install
如果系统以前已安装了旧版本的perl的话，替换系统原有的版本。
[root@akinlau perl-5.16.1]# mv /usr/bin/perl /usr/bin/perl.bak
[root@akinlau perl-5.16.1]# ln -s /usr/local/perl/bin/perl /usr/bin/perl
再看看是不是最新的版本
[root@akinlau perl-5.16.1]# perl -v
