[R-SIG-Mac] gfortran: command not found

[Spencer Graves]

Hello, All:


	  "R CMD check KFAS" under macOS 11.7.8 (the latest version that will 
run on my aging Mac) complains "gfortran: command not found".


	  I just upgraded to R 4.3.1 and installed 
"gfortran-12.2-universal.pkg" per 
"https://cran.r-project.org/bin/macosx/tools/".  I expected this to 
solve the problem.  It didn't.


	  Suggestions?
	  Thanks,
	  Spencer Graves


p.s.  This is my fork of KFAS, available at 
"https://github.com/sbgraves237/KFAS".  "sessionInfo()" appears below.
