Question about ports

[Pierre LeBlanc]

Hello,

I'm new to the port collection and updating ports with CVSup but I managed to 
update the ports of my FreeBSD 4.10 system using CVSup.

Now, I want to upgrade Perl to version 5.6 and I notice there is a perl5 port 
in the list I`ve seen on:

ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-4.10-release/

But this port is not on my system and to understand how to get perl5 in my 
port collection, I searched on the Internet for several hours without success.

Can you refer me a specific page or a chapter in the FreeBSD manual that 
describe how to do it?

Thank you,

Pierre LeBlanc
