[R-SIG-Mac] Nightly dmg builds

[Peter Cowan]

The night build page <http://R.research.att.com/>, conveniently
include a dmg build of R-devel (2.10).   However, I notice that the
current dmg, is from a revision 48594, which is May I believe.  Would
it be possible have a more recent revision package as a dmg?

Also, what is the preferred method of installing the tar.gz files?  I
was unclear how to use them in a fashion that would allow me to use
Rswitch to switch versions.

Thanks for the time and resources it takes to provide the nightly builds!
