I'm a little concerned about that wording change. I proposed the current wording and footnote because the situation is dynamic and is not so cut and dried.  For one, Apple could at anytime fix their Tcl/Tk.  Another, ActiveState could issue a new (and presumably better) patchlevel of 8.5 (rather than 8.5.9).  Third, users need to be aware that ActiveState Tcl/Tk comes with its own license which may not be compatible with their usage (a warning to be added in a forthcoming update to the mac/tcltk web page).  As it stands, the Download page, the Installer Welcome message, the Installer readme, and the last ditch IDLE warning message all point the user to one place for current information.  Yes, the download page can be easily updated but I could see a duplicated but distilled recommendation taking on a life of its own.  But I concede that my concern may be misplaced.
