No updates needed to update system to 8.2-RELEASE-p6 but still on 8.2-RELEASE-p3

[Antonio Olivares]

Dear kind folks,

I am getting more and more as to what is needed to keeping a system
running in optimum conditions(updating ports & userland too).  I was
just updating ports, but neglecting the new userland tools & kernels.
I have successfully run make buildworld & make installworld, and the
steps to run newer userland + kernel.  Also one can use freebsd-update
fetch & freebsd-update install and it will install binary
updates(avoid compiling).  I have done this on my 8.2 amd64 machines,
but somehow the finished command says that it is ready to run
8.2-RELEASE-p6, but I reboot and am still in 8.2-RELEASE-p3.  Is there
a way to do it, other than doing it from source(es)? through
freebsd-update utitlity?  I don't understand some suggestions in forum

I had gotten the error message:
Installing updates...install: ///usr/src/lib/libc/gen/libc_dlopen.c:
No such file or directory
 done.

and overcame it with

# mkdir -p /usr/src/lib/libc/gen

and rerunning freebsd-update fetch and freebsd-update install but
rebooting still gives -p3 kernel:

As always I thank all users for advice/suggestions/comments.  I have
