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.

Dear Simon, I received an email recently from a user trying to install the Rcmdr package under OS X 10.8 (Mountain Lion). It materialized that he was unable to install Tcl/Tk 8.5.5 from the R for Mac OS X Development Tools and Libraries page because his security settings didn't permit installation of software from "unidentified" developers. The problem was solved by resetting this option temporarily. I notice that the R Mac OS X binary itself is now signed to circumvent the problem, and wonder whether the same thing can be done for the Tcl/Tk that's provided -- or if not whether instructions for proceeding in Mountain Lion can be added to the web page. Depending on how the issue is resolved, I may add an instruction to the Rcmdr Mac installation notes.
