pkg_updating -d

[Peter Clark]

Hello,

I am new to using pkg_updating -d to look at new entries in /usr/ports/UPDATING. From what I have read I should be able to just use:
# pkg_updating -d 20130301  (for example)

And that should give me everything in /usr/ports/UPDATING newer than that date. When I run that command I get:
root at monitor:/ # pkg_updating -d 20130301
root at monitor:/ #

When I try # pkg_updating -d 20130201
root at monitor:/ # pkg_updating -d 20130201
root at monitor:/ #


When I try # pkg_updating -d 20130101
root at monitor:/ # pkg_updating -d 20130101
root at monitor:/ #


When I try # pkg_updating -d 20121201
root at monitor:/ # pkg_updating -d 20121201

  The pcre library has been updated to version 8.32.  Please
  rebuild all ports that depend on it.

  If you use portmaster:
        portmaster -w -r pcre
  If you use portupgrade:
        portupgrade -fr devel/pcre
  If you use pkgng with binary packages:
        pkg install -fR devel/pcre

Now that confuses me even more, it only returned one of the 2 advisories on 12/11/2012.

I am running:
9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec  4 09:23:10 UTC 2012     root at farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

I have "portsnap fetch update" today.


Any ideas on how I can correct this behavior?

Thank you,

Peter
