Compiling GC 3.2 seems to require libgwengui-gtk3-0, but that is not in
the ubuntu 16.04 repository. When I tried to add a later version from
debian, I ended up having to upgrade all things related to aqbanking,
which eventually killed other things.
I have eliminated aqbanking to get past it, but I really need that
function. Is there a solution to this?
