The OP should note as well that updating from 4.x to 5.x by compiling
from source is not the easiest way of going about things.  The
src/UPDATING file from HEAD says this, hidden such long way down the
file that most people will probably have got bored and given up
reading before they get to it:

        To upgrade in-place from 4.x-stable to current 
        # 5.x uses more space than 4.x.  Also, the location of kernel
        # modules has changed.  If you are installing 5.0 onto a 4.x
        # system, you'll need about 30MB of free disk space on your /
        # partition.  If you have less than this, you may encounter difficult
        # to back out of problems with this procedure.  If /tmp is on
        # the / partition, you may want to completely remove all its content
        # before upgrading, as this can be a common source of shortage of
        # space on /.

        make buildworld                                 [9]
        make buildkernel KERNCONF=YOUR_KERNEL_HERE      [8]
        cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2]
        make installkernel KERNCONF=YOUR_KERNEL_HERE
        cd src/sys/boot ; make install                  [6]

        make installworld
        mergemaster                                     [4]

and the several subsequent pages that expand on the numbered points
therein. See



  (5.1-RELEASE-pN, RELENG_5_1)

Once you've upgraded your base system, you'll definitely need to
install 4.x-COMPAT libraries and you'll probably end up needing to
reinstall all of your ports.  Over all, you may well find it better to
back up your /home area and any other data you don't want to lose,
wipe your system and re-install 5.x from scratch, but that's a
judgement you'll have to make for yourself.
