Thanks Brian.  Tried that just now --- and of course it didn't work.
(*Nothing* ever works for me! :-( )  In more detail --- I found that
I didn't *have* a .Renviron file.  So I created one, with the single
line

	R_LATEXCMD=latex

But I got the same error situation as before.  Is there any other action
I need to take to get the system to notice my ~/.Renviron file?

I checked that

	> Sys.getenv("R_LATEXCMD")

now does indeed return "latex".

Be that as it may, I tried the expedient of sudo editing the Renviron
file in R_HOME/etc/i386 and changing ``false'' to ``latex'' in the
definition of R_LATEXCMD.

And *that* worked, at least.

I am cc-ing this message to the R-sig-mac list.
