Comment (by kencu):

 Ah - well there is a bit of a learning curve to this, but it's easily
 within the reach of anyone interested. And the more contributors we have,
 the better.

 The portfile is where all the instructions are. Find it like this `port
 file upc`. You can edit it in place with your favourite text editor. I use
 bbedit.
 {{{
 bbedit `port file upc`
 }}}
 will open it up for you. Then look around a bit, get your bearings, and
 see if you can make sense of things. The configuration lines are easy
 enough to find. You can make some changes as above, if you see what makes
 sense to you to do.

 If you really mess up, just `sudo port sync` and everything will be put
 back to it's original state.

 If you fix it, save your changes somewhere or they will get overwritten
 next time you upgrade / sync.

 There's obviously a lot more to this than what I've written here, but if
 you have any programming experience at all, this will get you started. The
 macports website has lots and lots more information.
