Hello:
"R CMD build KFAS" under macOS 11.7.8 stopped with:
using C compiler: ?Apple clang version 12.0.5 (clang-1205.0.22.9)?

My web search suggests several different ways to fix this problem, but I don't know which to try.
Suggestions?
Thanks,
Spencer Graves
p.s. I have both "brew" and "port" installed. I recently used "port" to upgrade another software package. A web search suggested the following:
sudo port install gcc48
sudo port select -set gcc mp-gcc48
