While the installation from http://www.kyngchaos.com/files/software/frameworks/rgdal-0.6.29-1.zip works fine the installation of rgdal from CRAN on MACOSX does not work, despite my previous message that this issue was solved as well
Please do read the error message:

The image that is not found is libR.dylib, the main R dylib against which rgdal.so is linked. So this is still an issue of your R installation, possibly a multi-architecture issue (is libR.dylib the i386 version, guessing - is libR64.dylib the 64-bit Intel version?). Could any OSX users who are using CRAN extra rgdal please help Agus to resolve this - it could be that local path modifications are hiding libR.dylib, or that R was installed 64-bit only, and the INSTALL_opts= argument to install.packages() was not set correctly? I assume that the CRAN extras OSX rgdal binary is built against a standard R OSX Intel install, which is multi-architecture. For a fully updated rgdal, the best combination remains installing the full GDAL framework from Kyngchaos, the full tools collection: http://r.research.att.com/tools/ http://cran.r-project.org/bin/macosx/tools and install from CRAN source. For a lab, the instructor would rather build a local OSX rgdal binary package using the tools collection on one development machine with all the correct path variables set (R CMD check rgdal; R CMD INSTALL --build rgdal), paying attention to multi-architectures, and distribute to lab machines from there. This means that the lab instructor can keep rgdal updated if need be, as both Kyngchaos and CRAN extras rgdal OSX binary packages typically lag CRAN source. Please also note that there are very many very old GDAL binaries out there that users pick up and apply, missing all the subsequent bug-fixes and improvements - GDAL 1.8.0 release candidate 1 is now out, so we are looking at an upgrade to 1.8.0 during January, which Kyngchaos will most likely pick up quickly, probably with a current rgdal binary.
