[R-SIG-Mac] Tcl/Tk

Hi Dan,

I remember now, I had included Tcl/Tk when I installed last time.  
Still, I grabbed that straw, downloaded the installer and did a  
default install (I checked, it included Tcl/Tk).

However I'm still not out of trouble. I hope I'll find a solution  
less disturbing than reinstalling OS X...

This was after a restart immediately following reinstallation of R
