That sounds good in principle, but as you might already know a large part of our work in this forum has been first trying to get KStars up and running on a mac in a usable format and then trying to get all the other programs it depends upon and uses to a place that kstars will be able to find them. And then we worked to get it all wrapped up and portable in a single app and dmg. It required us to rewrite a significant amount of kstars code and to carefully write a build script to take care of all of that work to get it ready so that all users would need to do is install by dragging and dropping the app. That is not to say that using another build method would not work, just that there are currently a lot of steps to get it working.
Home-brew right now is your best bet of course because kf5 is currently working with it, but yes it would be an excellent goal to get that up and running on finks and macports. In our script, we include two methods for building kstars, one that relies on homebrew and another one that relies heavily on a tool called craft. The craft method is particularly friendly becase it automates the process quite a bit more and installs many of the latest versions of the dependencies in the right order, but we still need home-brew for some things as well, and some file and folder copying are still required.
All of that being said, here is an idea. Could you try ruunning our build script on the powerbook? I would be curious to see if that works. Regardless, if you want to get it working on homebrew, macports, or fink without our build script, you will probably want to reference our script to see what steps we took to get it working.

Thanks and let me know about any progress or problems. Good luck!
Thanks,
