pkg upgrade question

[Leslie Jensen]

If I do

portsnap fetch update
pkg version -vIL=

I'll get the result below for ports that needs to be upgraded

Building new INDEX files... done.
cups-client-1.7.3_2                <   needs updating (index has 1.7.3_3)

libgcrypt-1.6.1_5                  <   needs updating (index has 1.6.2)
noip-2.1.9_2                       <   needs updating (index has 2.1.9_3)
pkg-1.4.3                          <   needs updating (index has 1.4.4)
squidview-0.80                     <   needs updating (index has 0.81)

If I do
pkg version

I'll see the same packages marked with a <

Then I do
pkg upgrade


Updating FreeBSD repository catalogue...
FreeBSD repository is up-to-date.
All repositories are up-to-date.
Checking for upgrades (1 candidates): 100%
Processing candidates (1 candidates): 100%
Checking integrity... done (0 conflicting)
Your packages are up to date.

And it says that all packages are up to date!

Is it because no packages are available for those ports at the moment?

I'm a bit confused.

Thanks
