[R-SIG-Mac] Loading rgl fails on 2.7.0

[Prof Brian Ripley]

The URL is for a binary package from CRAN.

So the 'what I am doing wrong' is attempting to use CRAN binaries with a 
non-CRAN build of R.  I've succeeded with type="source".  That repository 
('http://cran.r-project.org/bin/macosx/universal/contrib/2.7) is not 
current -- it has not been touched for 2.5 months.

There is no 'R 2.7.0' as yet: this is R-devel and it is somewhat unstable 
-- there is a new quartz() device and I fixed a segfault since the version 
mentioned and there are graphics changes in progress that may lead to 
incorrect output until finished.  You should expect to have to install 
packages from source in the exact R version you use -- that is if you 
update R-devel you may need to re-install packages.  (I only know that to 
be true of packages providing graphics devices, but the principle is 
general.)
