Dear Brian, if it is able to test the compilation of the quartz device by calling quartz() in R - this works. Calling xcodebuild -version gives me: Xcode 4.6.3 and clang --version gives me LLVM 3.2svn indeed. My prime target was to be able to use OpenMP 3.1 which is actually only available (freely) in gcc >= 4.7. Is there a possibility to install, check and reinstall all CRAN packages in R?
