See your installer log - it will explain it.

You don't have Tcl/Tk installed. My wild guess would be that you have  
upgraded to Leopard from an older system that had /usr/local/lib and  
the upgrade (or installation of Xcode 3) created an infinite link loop  
which prevents anything to be installed (including TclTk). See also

and

If that is the issue, correct it and re-install R.
