Completely removing a port

[Matt Juszczak]

Hi all,

I am about to remove the amavisd-new port from our main mail server. 
We've recently setup two relay servers and do not need the port anymore.

Problem is, I know that the amavisd-new port installed a lot of packages 
along with it, and if I just do `make deinstall clean` in the port, its 
only going to remove amavisd-new first, not the dependencies it installed 
to work correctly.

Is there anyway I can deinstall the port and say "remove all packages that 
depend on amavisd-new and amavisd-new ONLY" (so it wont affect other 
stuff).

Thanks,

Matt
