This morning, I installed qalculate on my MacOSX system.

High Sierra, MacPorts up-to-date, version 2.4.2.

When I try to launch qalculate, I get the following error...

~ $ qalculate-gtk

(qalculate-gtk:1638): Gtk-WARNING **: cannot open display

I played around with the DISPLAY environment variables as well as
installing the mac port, xorg-server. However, the only thing that worked
was installing XQartz and then launching qalculate from its terminal

This is not an ideal solution since the graphics of the app are very poor.

Is there another solution that would allow qalculate to open with Mac
graphic quality?
