install tcltk

Rdatatable/data.table#5823 discusses release 1.15.0 which caused a revdep check failure for a package that depends on tcltk, which is not installed on monsoon.
I sent an email to ask-arc@nau.edu which asked them to create a module for tcltk.

I would like to build my own R (not use module R, not use conda), and I actually do that under ~/R/R-4.3.2 etc.
Using that R I built, capabilities("tcltk") is FALSE.
When I use R source code ./configure --help I see

--with-tcltk use Tcl/Tk (if available), or specify its library
dir [yes]
--with-tcl-config=TCL_CONFIG
specify location of tclConfig.sh []
--with-tk-config=TK_CONFIG
specify location of tkConfig.sh []

and when I run configure via params.R I see

checking for tclConfig.sh... no
checking for tclConfig.sh in library (sub)directories... no
checking for tkConfig.sh... no
checking for tkConfig.sh in library (sub)directories... no
checking for tcl.h... yes
checking for tk.h... yes

so it seems the C headers are found, but not the Config shell scripts (tkConfig.sh and tclConfig.sh), so I asked where those can be found.

this is resolved by telling R configure where to find tcl/tk config.sh 18feb86

 ./configure --prefix=$HOME --enable-memory-profiling --with-tcl-config=$CONDA_PREFIX/lib/tclConfig.sh --with-tk-config=$CONDA_PREFIX/lib/tkConfig.sh

tcltk2 works now, not sure why,
