Dear Jean Louis, I agree with Jean-Julien's message. I just want to add a couple of points.

I agree with Jean-Julien that uninstalling Frescobaldi should not be necessary. Anyway, if you have doubts on using MacPorts, please see the guide at https://guide.macports.org It seems to me that now your immediate problems are solved. If that's not true or if anything else arises you can write to either the LilyPond or the Frescobaldi list. I admit I tend to disappear for long periods (due to personal and professional reasons) and I'm very sorry for that: if that happens you can write to me directly to get my attention. Best wishes.
