I often have multiple Tcl/Tk installations on a system for testing purposes, and quite a few times I have accidentally specified --tclsh for the wrong Tcl/Tk installation to Tcl::pTk, rather than whichever one Tcl.pm is currently using.
I wonder if this could be prevented: when installing Tcl.pm dependents (Tcl::pTk, Tcl::Tk, etc.), why not have them go through Tcl.pm to check for Tcl/Tk versions and extensions, rather than relying on a possibly-incorrect path to tclsh? Would it be okay for Tcl.pm dependents to `require Tcl` from inside Makefile.PL (only when the --test-for-tk check is requested), or is it considered universally "bad" for Makefile.PL files to try using dependencies this way? Was there a reason this approach was not used in the first place? Christopher A. Chavez
