Thanks, indeed, as part of full re-install for R 4.2.0 package builds the Tcl/Tk libraries were missing. Now fixed and summarytools check with

NOTE Note: found 78 marked UTF-8 strings Status: 1 NOTE I'll just repeat the important link that Tomas posted: https://cran.r-project.org/web/packages/external_libs.html On a slightly orthogonal note (not related to the question other than it involves tcltk): I'd like to point out that Tcl/Tk is often not available on computing servers, so I would recommend packages that do not provide GUI tools to avoid dependence on tcltk if not strictly necessary as it prevents the use in headless HPC environments.
