Port version vs PKG version

[Boris]

Hi all,

Maybe a dumb question but how quickly should a new version of a package
become available through pkg ?

I am asking as I just spent sometime getting rrdtool to work which I
finally did by installing the port.

http://www.freshports.org/databases/rrdtool/ shows version 1.4.8_4 from the
30th of Aug while the package still shows version 1.4.8_2
pkg search rrdtool
[..]
rrdtool-1.4.8_2
[..]

#pkg update
Updating FreeBSD repository catalogue...
FreeBSD repository is up-to-date.
All repositories are up-to-date.

As of:
#date
Thu Sep  4 22:57:43 EDT 2014

Note: I had to upgrade as 'rrdinfo' and 'rrdupdate' segfault

Thanks in advance,

Boris
