Port GUI Config

[Donovan R. Palmer]

I went to compile a programme in the port tree tonight. When I did so, a GUI popped up with different options. No probs.  However, later I decided I wanted to compile it with different options. When I go to compile it, the GUI doesn't pop up any more, so I assume it is using the options I picked out in the first place.  Is there a way to bring back this GUI so I can select different options? TIA
