Found the problem:
I said I had built and installed the software in this order: 1 jack, 2 qjackctl, 3 fluidsynth, 4 qsynth
In fact I did it in this order: 1. fluidsynth, 2 jack, 3 qjackctl, 4 qsynth
So... I unwittingly compiled fluidsynth without any jack support... oh well...
Now things start up correctly. All I have to do now is to learn how to use jack to plug things together.
Hi again,

Thanks for all your help.
