[R-SIG-Mac] procedure to ship libomp.dylib run-time with package

[Kasper Daniel Hansen]

If you read the next couple of sentences on that page, it says

The following are links to libomp OpenMP run-time built from official LLVM
release sources using Xcode compilers. They are signed and support macOS
10.13 (High Sierra) and higher. All tar-balls contain the system tree
usr/local/lib and usr/local/include so the recommended installation is to
type in Terminal:

    curl -O
https://mac.r-project.org/openmp/openmp-14.0.6-darwin20-Release.tar.gz
    sudo tar fvxz openmp-14.0.6-darwin20-Release.tar.gz -C /


I think that is pretty clear? Note the -C / as part of the last line, that
tells tar where to put it on the system.
