[R-SIG-Mac] Updated R.dmg Image for R-1.9.1

[Simon Urbanek]

A slightly modified R.dmg image is now available from CRAN (main AT 
mirror now, others should follow as the changes propagate). To clarify 
what happened here is the history of the R.dmg images of R-1.9.1 so 
far:

1) first release - ca. 20MB (2004/06/26), installer same as in R 1.9.0
contained R-1.9.1.pkg, libxml2.pkg and a ReadMe file
both R.app and framework were packed in one package; some problems 
because it changed rights of the Applications folder and could case 
problems on non-standard systems

2) second release - ca. 40MB (2004/06/29)
new installer, but contained both the package sources and the actual 
packages. libxml2 was marked as "required" which caused problems on 
Panther (use "sudo rm -f /usr/local/lib/libxml2*" on Panther if you 
installed it)

3) third, now current release - ca. 20MB (2004/07/03)
new installer (the image contains R.mpkg meta-package and a folder 
Packages) - double-click on R.mpkg to install
allows custom installation of all three parts (you can click on 
"customize" after selecting target volume - the choices are R.app, 
Framework and libxml2). limxml2 is not selected by default, so it works 
fine on Panther.

Those having problems with earlier versions, please try the latest 
installer and report any failures. If you have problems *installing* R, 
please don't forget to include the installer log in your report 
(File->Show Log)!
