freebsd-upgrade from 6.2 to 6.3 errors

[Gert Lynge - Inter-Data A/S]

Hi

Just followed http://www.daemonology.net/blog/2007-11-10-freebsd-minor-version-upgrade.html very careful to upgrade my box from 6.2 to 6.3 (btw. great work by Colin Percival). Now uname shows:
# uname -a
FreeBSD ws.inter-data.dk 6.3-RELEASE-p1 FreeBSD 6.3-RELEASE-p1 #0: Wed Feb 13 02:56:56 UTC 2008     root at i386-builder.daemonology.net:/usr/obj/usr/src/sys/SMP  i386

...as expected. The problems is that at the final "sh freebsd-update.sh -f freebsd-update.conf install" it said:
# sh freebsd-update.sh -f freebsd-update.conf install
Installing updates...ln: ///usr/share/man/man4/em.4.gz: No such file or directory
rmdir: ///usr/src/gnu/usr.bin/gzip: Directory not empty

Should I be concerned?
The system seems to run fine, but man pages (i.e. "man em" or "man arp") still states "FreeBSD 6.2" at the final line. Is this wrong?
What about the two errors. Do I need to clean something up after freebsd-update?:

# ls -l /usr/share/man/man4/em*
-rwxr--r-x  1 root  wheel  5391 Jun 29  2007 /usr/share/man/man4/em.4
-r--r--r--  2 root  wheel  2879 Mar 14  2007 /usr/share/man/man4/emSAVE.4.gz

# ls -l /usr/src/gnu/usr.bin/gzip
total 64

Thank you in advantage...

With kind regards
