Steps to ensure compatibility between fink and macports

[David T.]

I am new to this list. I have had a macbook for three years now after moving from 20+years in the PC world with a smattering of Linux. I am running 10.5.6, and I have used fink for my limited open-source software needs (gnucash), but recently saw that others have been able to use MacPorts to create a Quartz version of Gnucash. Since I have a working version of Gnucash using fink, I am leery about just firing up Macports and trying the steps listed by others. Before I do this, I'd like to know with some certainty the steps I need to take to insulate the functional fink package from my fiddling around with MacPorts. I searched for guidance on fink/macports compatibility, but didn't find any clear outlines of how to ensure this. Has anyone got a clear set of steps and guidelines for me to follow to try using macports without messing up fink?

TIA,
David
