Dear Simon, Thanks for the quick reply. I tried to do what you suggested:
install_name_tool -id /Library/Frameworks/R.framework/Versions/3.1/Resources/lib/libquadmath.0.dylib /usr/local/lib/libquadmath.0.dylib But I got the following error messages: error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't open input file: /usr/local/lib/libquadmath.0.dylib for writing (Permission denied) error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't lseek to offset: 0 in file: /usr/local/lib/libquadmath.0.dylib for writing (Bad file descriptor) error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't write new headers in file: /usr/local/lib/libquadmath.0.dylib (Bad file descriptor) error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: can't close written on input file: /usr/local/lib/libquadmath.0.dylib (Bad file descriptor) The first error (Permission denied) can be solved by using "sudo" I suppose. But I am not sure what caused the other three errors. Do you happen know what may have been the root of the errors? Thank you again.
