I've little idea either but this may be to do with the fact that we don't 
install things as setuid root and Macports does sometimes. When things 
require privileged networking operations they therefore sometimes need to 
be sudo'd on Homebrew. Try that and see if it helps.

that i call the formula with sudo?
