[R-SIG-Mac] installing Tcl/Tk 8.5.5 for X11 on Mountain Lion

[John Maindonald]

All that is needed is to do a right click (or its equivalent),
where for "approved" software a left click works the needed
magic.  The user is then asked whether, notwithstanding 
the lack of an Apple imprimatur, they wish to proceed.

A note to this effect might accompany any software that is
to be downloaded.  Most Mountain Lion users will rather
quickly latch onto this.
