If you running 4.6 you shouldn't upgrade your ports tree, upgrade to, at 
least 4.8 or stable first.
You can learn this from:

or

You can use portupgrade, it's in /usr/ports/sysutils/portupgrade but 
then again I would recommend upgrading FreeBSD to 4.8 or stable. You can 
learn on how to use portupgrade here:
