In case someone is having trouble with building odin on an arm64 processor mac and getting this error when running the executable
dyld[76430]: Library not loaded: @rpath/libLLVM.dylib
Reason: no LC_RPATH's found
Node: I have installed llvm-20 with macports maybe that is what is causing the issue.
I solved the issue by linking the correct LLVM.dylib with running this after building odin
install_name_tool -change @rpath/libLLVM.dylib /opt/local/libexec/llvm-20/lib/libLLVM.dylib odin
