perl - update

[ajtiM]

Hi!

My system: FreeBSD 8.1

I like to update perl to higher version and I don't want to screw up...
I red /usr/ports/UPDATING:

"perl-after-upgrade" script supplied with lang/perl5.12

If I update to perl 5.12.3 is it enough that I run above script, please?
In /etc/make.conf I have:
# added by use.perl 2010-11-05 17:40:46                                                      
PERL_VERSION=5.8.9                       

I have above from version 8.0. Do I need to change version from 5.8.9 to 5.12 
or to 5.12.3?

Thank you very much.

Mitja
