Sorry to jump in here so late but I just gave this a try. I usually install rgdal from CRAN on windows or download the binary from http://www.kyngchaos.com for Mac. I wanted to try your method from building from source since the directions were so clear and understandable. This is the first time I have done this and I am not very terminal savvy. I ran the last command above and get this message: * installing to library ‘/Library/Frameworks/R.framework/Resources/library’ * installing *source* package ‘rgdal’ ... gdal-config: /Library/Frameworks/GDAL.framework/unix/bin/gdal-config /Library/Frameworks/R.framework/Resources/bin/config: line 143: make: command not found /Library/Frameworks/R.framework/Resources/bin/config: line 144: make: command not found /Library/Frameworks/R.framework/Resources/bin/config: line 220: make: command not found /Library/Frameworks/R.framework/Resources/bin/config: line 143: make: command not found /Library/Frameworks/R.framework/Resources/bin/config: line 144: make: command not found /Library/Frameworks/R.framework/Resources/bin/config: line 220: make: command not found checking for gcc... no checking for cc... no checking for cc... no checking for cl... no configure: error: no acceptable C compiler found in $PATH See `config.log' for more details. ERROR: configuration failed for package ‘rgdal’ * removing ‘/Library/Frameworks/R.framework/Resources/library/rgdal’ It seem to be looking for the C compiler among other things. Can you provide any help on this?
