[R-SIG-Mac] R , RCPP unsing MACOS ventura

[Simon Urbanek]

Federico,

given that Homebrew is likely the cause for the mess, advising to install a custom installation seems like a very bad idea. It is likely very dependent on the versions of the tools from Homebrew which is what breaks. Therefore I would strongly advise against it (unless you know what you are doing, but then if you do - you know how to fix it).

So to the list readers - please do NOT follow the advice for custom flags unless you know what it does and how to maintain it. If you use custom tools (which is fine for experts), you are likely to have problems down the road since such installations are not maintained by Apple and will break and will need fixing.

Cheers,
Simon
