I am trying to make a plot in julia on a headless ubuntu instance and I am running into the following error. I have the feeling that it is trying to print to a screen instead of write to a file. But I am not sure what I am doing wrong.:
ENV["GKSwstype"]="100";
using GR
 x = [-3.3 + t*0.1 for t in 0:66];
 y = [(t^5 - 13*t^3 + 36*t)::Float64 for t in x];
plot(x, y)
ERROR: error compiling #plot#27: error compiling plot_data: error compiling clearws: could not load library "/home/ubuntu/.julia/v0.6/GR/src/../deps/gr/lib/libGR.so"
libXt.so.6: cannot open shared object file: No such file or directory
Stacktrace:

@TDRoss : even on a headless system, you will have to install some requirements. Please refer to our GitLab-CI configuration here: https://github.com/jheinen/gr/blob/master/.gitlab-ci.yml
You probably need libgl1-mesa-dev libglu1-mesa-dev xorg-dev
