[WIP] update mac configure script and add messaging about common port forwarding issue

update mac configure script and add messaging about port forwarding until we maybe use a better solution like how libtorrent does this, or RPC & UDP like this https://github.com/bmuller/rpcudp to avoid most port forwarding issues.
no the easy_install was never called, that's the point.  when you brew install python, you get pip with that.  when you do virtualenv from root, you get pip in env/bin/pip too.
