problematic MACOSX_DEPLOYMENT_TARGET

Christoph,

please make sure you have:
- Xcode 2.4 or higher installed (2.5 recommended)
- you are using Apple's compilers
- MACOSX_DEPLOYMENT_TARGET is not explicitly set (e.g. try  
Sys.getenv("MACOSX_DEPLOYMENT_TARGET"))

If all the above is true, please send me the output in Terminal:
which gcc
gcc --version

then try
Sys.setenv("MACOSX_DEPLOYMENT_TARGET"="10.4")
before installing a package from source.

Thanks,
Simon

Dear list,

after having installed R-2.8.0 on Mac OS 10.4.11, I get an error  
message when I try to install the source of a package (please see  
below). I was trying to find a solution on the web, but my  
understanding of the architecture of Mac OS is to weak to make  
something out of the hints I found. Can someone point me towards  
an easy-understandable solution to the problem? What do I have to  
change exactly and how can I do it?

Thank you in advance!
