[R-SIG-Mac] Tcl/Tk

I just tried two things that required Tcl/Tk (acronym I've seen a lot  
lately, but that means next to nothing to me): Grass 6 and R packages  
tcltk and PBSmodelling. Grass simple vanished before completing its  
launch, and this is what I got from within R:

 > library(tcltk)
Loading Tcl/Tk interface ... Erreur dans fun(...) : Can't find a  
usable init.tcl in the following directories:

This probably means that Tcl wasn't installed properly.
Erreur : .onLoad a échoué dans 'loadNamespace' pour 'tcltk'
Erreur : le chargement du package / espace de noms a échoué pour 'tcltk'

For some reason I thought Tcl/Tk came standard with Tiger. I cannot  
find trace of it on my HD. I've used Spotlight but I think this does  
not search in the invisible folders. I looked manually in /usr and  
did not see it, but I could have missed it.

Was I wrong to assume it came with Tiger? Was it like XWindow, a box  
I had to click to have it included (in which case I'm not sure I  
clicked it). I also remember seeing an option for Tcl/Tk when I  
installed R 2.3, and I thought I selected it.

Anyway, although answers to the above will satisfy my curiosity, my  
main question is: I downloaded TclTkAqua-8.4.10 from

Can I do any harm in installing this? Is it a solution to the  
problems above? Is it the solution you'd recomment?

Thanks in advance,
