[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

If the system has previously installed the old version of perl, replace the original version of the system.
[Root @ akinlau perl-5.16.1] # mv/usr/bin/perl. bak
[Root @ akinlau perl-5.16.1] # ln-s/usr/local/perl/bin/perl/usr/bin/perl
