R 'records' its tcl/tk version chosen via 'configure' when building. To differentiate between 8.6 and 9.0 here Wayne and/or you likely need to rebuild R. For what it is worth, my sources for the Debian packaging are still at 8.6 (explicitly selecting it) and hence are the Ubuntu binaries at CRAN. Debian does have tcl8.6-dev along with tcl9.0-dev. | - I haven't built tcl/tk 9.0.1, and like Wayne, would like to avoid | that. Is there a Github action that would install it? I would recommend a container, and starting from one of the standard 'how to build R setups'. A possible one is my 'daily R patched' (drp) one at https://github.com/rocker-org/drp which builds weekly. You would just have to change tcl (and presumably tk) to 9.0 in the Dockerfile at https://github.com/rocker-org/drp/blob/master/Dockerfile in line 57 and 64 replacing, respectively, tcl-dev with tcl9.0-dev and tk-dev with tk9.0-dev. [ Debian tends to change such common infrastructure packages in a coordinated wave (called 'transition'), and we have not had one yet for tcl/tk 9.0. ] Rebuilding the container (which one can do in an action) will get you r-patched with the 9.0 versions of tck and tk which should allow some client testing (in 'loon') to accommodate accordingly (which another action can call). Of course just doing it locally also works and is easier. While at it, it would be nice if the package could (just like 'rgl' does) work around a missing x11 at package install, currently headless setups need to explicitly wrap this in xvfb. Hope this helps. Feel free to ping me off-list if the Docker use is unclear yet is something you want to try.
