Many thanks for your clarifications, Ralf.
But if

.../...

then  we are just discarding alternative 1 in my first post:
"> setRepositories(ind=1:2)
> install.packages('rgdal')
"
Also, what about homebrew? is this not a good way to make this type of
things easier on Macs?

Finally, where you say
> BTW: "Linux Techies"  should have no major probs with Mac, given that the Mac system commands are more or less the same as for Linux systems
The problem is that most mac users I've had as students are not
Techies on anything. Otherwise, Macs are wonderful machines.

> This option should always be mentioned in case binaries do not work on a specific system (Tiger, Panther, Leopard etc) - and apart from that it can take a bit after rgdal binaries are available on kyngchaos after R updates (and some people may not want to wait after future updates). In addition, the installed tools may also be necessary for the R commander GUI, GIMP and other programs or if you need to install other packages from source.
> So the way to go is:
> 1. Install GDAL Framework on kyngchaos GDAL 1.7 Complete
> 2. Install R AND all tools for Mac: Gfortran gfortran-4.2.3.dmg TclTk tcltk-8.5.5-x11.dmg Developer pack devpack4-darwin8-bin4.tar.gz
> 3. Install Xcode tools - either from DVD that ships with every mac or after free registration here http://developer.apple.com/programs/register/ (the Xcode tools are also recommended in the Mac OS X FAQ for R http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html)
