R @4.1.2_1: Build fails on Intel iMac, Monterey 12.2.1, Xcode 13.2.1, SDK 12

Building R @4.1.2_1 on Intel iMac running Monterey 12.2.1 with Xcode 13.2.1, SDK 12 gives the following error:

This seems to be a bug associated with MacOSX12.1.sdk. I found if I symlink MacOSX12.sdk to MacOSX11.3.sdk, R can build successfully.

R with the default variants builds fine on my system, what variants are you using?

[ryandesign (Ryan Schmidt)]

i0ntempest, does your system also use the macOS 12 SDK? This peculiar error has been reported in other MacPorts tickets and elsewhere when using the macOS 12 SDK. A peculiar-looking fix has been suggested; see comment:ticket:63877:8. I don't know if one or both of those parameters are appropriate to use here or if maybe some better solution has been found in the mean time.

The only difference seems to be clang 12 vs 13?
