jail setup

[dave]

Hello,
    I'm setting up a jail under 5.2.1 to run pure-ftpd in. I did the
following:
cvsupped the source
cd /usr/src
make world DESTDIR=/usr/jail/ftp
cd etc
make distribution DESTDIR=/usr/jail/ftp
then linked /dev/null to kernel inside the jail area.
I'm following an onlamp article at:
and understood that sendmail and perl and some other items would be
available. When i do a pkg_info from within the jail there aren't any
packages. did i miss a step? Is there something i should have installed to
make this go easier?
Thanks.
Dave.
