hi, installing on linux using conda-forge gives the following error anaconda3/envs/gt/bin/gtk-query-immodules-3.0: error while loading shared libraries: libXcursor.so.1: cannot open shared object file: No such file or directory ERROR: Failed to complete gtk3's post-link script. To fix this, activate the environment and run: glib-compile-schemas "/home/anaconda3/envs/gt/share/glib-2.0/schemas" gtk-update-icon-cache -f -t "/home/anaconda3/envs/gt/share/icons/hicolor" gtk-query-immodules-3.0 --update-cache unfortunately running the three suggested lines gives another error gtk-query-immodules-3.0: error while loading shared libraries: libXcursor.so.1: cannot open shared object file: No such file or directory and running graph-tool also gives an error any ideas?
