Yeah, I think you have duplicate LC_RPATH load commands. In that case, your binaries can be corrupted by install_name_tool during "make install." To check if that is your case, you can run this on the binary before installation to see if you have duplicates. otool -l app | grep -A2 LC_RPATH If the duplicates come from your own linker flags such as, -Wl,-rpath,/some/path, you may need to remove those. Otherwise, it would help if you can provide a minimal test case to reproduce the problem. It would also help if someone could report this corruption by install_name_tool bug to Apple. You are the second to come to this mailing list about this bug. Clint
