This is what I do (gtk3 +quartz). It takes a bit of effort, though, to 
ensure that all of the relevant gtk3 deps are also +quartz. If already 
installed as +x11, it takes a bit of manual intervention. Also, you 
probably want the adwaita-icon-theme.

Still, qalculate-gtk should look OK with X11, but I have not tested it 
recently. Using xorg-server works for other x11 ports on my computer, 
e.g., xlogo.
