	Yeah, I didn't/don't understand that, since I don't understand
	what ``proxies'' are.  I'm just hammering and hoping.  P'raps
	the IT person who will come by this arvo will be able to help
	me get this straight.  I shall discuss Prof. Ripley's advice
	with her.

	OK.  I'll get the CRAN release.  I'd still like to fix up the
	old tools issue, but.

	Did that.  'Mazing what I can do, once I know how! :-)
	It says version 2.5.  So, from what you said later in your
	email,
- search for Xcode
2.5 - download and install.

would seem to be up to date.

	I gave that a go just now, and it said:

	So I need to update my gcc.  But the FAQ says, in respect of
	C/C++ compiler (section 2.1.1) that I should download Xcode
	from http://developer.apple.com/tools/xcode/.

	And if my current Xcode (version 2.5) is uptodate, that won't
	make a difference, will it?  I'm puzzled.

	Well, I'm going to have a try at downloading the latest Xcode
	from the Apple site and see if that helps.

	Thanks for all your assistance.  I may well be bugging you
	again soon, I'm afraid.

		cheers,
