Indeed, this issue is specific to ppc64. The problem is that it's not  
possible to build ppc64 binaries of R on an Intel machine so we have  
to use another machine for the ppc64 build and that machine didn't  
have the latest Tcl/Tk installed. This should be fixed now so please  
try the updated nightly build tomorrow.
