如何升级linux vps自带的perl的版本到5.22.1版？

wget http://www.cpan.org/src/perl-5.22.1.tar.gz
tar zxvf perl-5.22.1.tar.gz
cd perl-5.22.1

as3:~/perl-5.22.1# ./Configure -des -Dprefix=/usr （设置安装目录为/usr,意思就是覆盖安装系统里原有的程序perl)
as3:~/perl-5.22.1# make
as3:~/perl-5.22.1# make install
as3:~/perl-5.22.1# perl -v (下面显示了v5.22.1，  说明版本成功升级到了v5.22.1)

This is perl 5, version 22, subversion 1 (v5.22.1) built for i686-linux

或按这里http://www.linux521.com/2009/system/200905/3095.html的做法也行，它是另外指定安装目录。
