	The way the Fates treat me, it will do no good with probability =

	I don't ***have*** 4.2 at all, as far as I can tell.  Simon
	Urbanek told me that I ***needed*** to use 4.2 in order to get
	things to build properly from source. He indicated that I should
	make the system ***use*** 4.2 by doing

		sudo gcc_select 4.2

	but as I said, this just tells me that 4.2 ain't there.

	Thanks.  I look forward to your report with baited breath.
