PORTREVISON lowers after devel/gettext's great bump

[Max Brazhnikov]

I updated today ports tree and several installed packages get newer than 
ports:

avahi-app-0.6.22_4          >  succeeds port (port has 0.6.22_1)
linc-1.0.3_6                >  succeeds port (port has 1.0.3_1)
ru-openoffice.org-2.4.0_4   >  succeeds port (port has 2.4.0_1)

seems for some ports the PORTREVISON has reset, for example:
http://www.freebsd.org/cgi/cvsweb.cgi/ports/net/avahi-app/Makefile.diff?r1=1.11;r2=1.12;f=h
