howto dissallow upgrade for specific port?

[Jesse Guardiani]

Howdy list,

I have a port that I do NOT want to upgrade: python-2.2.2
If I do upgrade it, some of the software on my system will
not work correctly.

However, I'd still like to use portupgrade -R on a few
ports to upgrade all dependencies EXCEPT python.

Is there a way to mark a port as non-upgradable?

Thanks.
